Fixed Bugs

54315 Incompatibility with SIEVE rules

When running OX App Suite 7.8.3 and 7.8.4 against a shared mail environment, SIEVE filter rules could unintentionally affect each other, for example auto-forward and vacation notice. This got fixed by retaining commented script content which is unknown to the 7.8.4 implementation.

54181 Config-cascade inconsistency for value pairs

Certain value pairs where not correctly distributed by the config cascade mechanism, especially those related to services that use oAuth for authentication. We solved this by making those properties config-cascade aware.

54136 Incorrect permission restriction when moving folders in Drive

When moving/copying a folder from a external storage service to folder of the primary OX Drive storage service, a permission related error was thrown. This got solved by properly setting administrator privileges to the creator of a OX Drive folder while copying/moving in folders from external services.

54133 Sharing dialog stuck when sharing locked file

When attempting to share a file which is locked, the sharing dialog did not close when canceling the operation. This got solved by handling potential errors related to locks when trying to share a file.

54069 Fuzzy fallback for unsupported languages

In certain cases the frontend language did fall back to german instead of english. This got fixed by setting a explicit fallback to en_US if the browser provides a unsupported language and no previously set OX language cookie.

54067 Outdated "unsupported browsers" message

OX App Suite UI did display incorrect recommendations for mobile browsers when using such as a desktop browser. This has been solved and we're now showing recommendations for mobile browsers only when using a mobile device.

54042 Unable to update dates with Japanese locale

When defining start/end dates at the calendar on mobile browsers, the supplied data did not get taken over to the appointment. This was caused by incompatibility of a date/time format library with specific languages and has been fixed by making sure the same date/time format is used at all related components.

54041 Missing schema information for database timeout errors

In case a database connection reported a communication failure or timeout, the specific database schema was not part of the exception. This has now been added to allow simple debugging of affected database clusters.

54034 Missing recipient when removing and modifying recipients

In cases where the original recipients (To, Cc) of a mail got removed during compose and re-added later, the resulting mail was sent without recipient information. This got fixed by properly handling events related to tokens that display participants.

53980 High CPU load caused by documentconverter

Changes to documentconverter led to higher than usual base CPU load. This impact got reduced by lowering a queue polling time to a value which offers a good compromise between queue responsiveness and "idle" CPU load.

In case a IMAP backend did close a connection due to technical issues or timeouts, the resulting stack-trace at OX App Suite middleware was rather generic. This has been improved in a way that we now show the related IMAP command to allow better debugging. This issue has to be validated in production environments that show such unexpected behavior.

53923 Quick reply disappears after the first reply

When using "quick reply" to answer a mail, this option will disappear. We changed the behavior in a way that the option stays available after using it.

53916 Adding local files opens camera App on iOS

When using OX App Suite UI with Safari on iOS, the action to add a local attachment resulted in immediate launch of the camera App. We now trigger a selection menu which offers to either use the camera or access existing photos on the device.

53913 Vacation notices could not be activated for aliases

When setting a vacation notice, it was not possible to define a alias address for the notice instead of the primary address. This got fixed by more consistent checks for mail aliases.

53688 Contacts with Katakana "yomi" fields were sorted as "other"

When using Japanese language settings and subsequently "yomi" contact fields, those contacts were sorted incorrectly as "other", which got solved.

53671 Specific mails produced empty printouts

When printing specific mails that define CSS, the created print version did not show substantial content. This got fixed by dropping certain CSS elements from our whitelist that could lead to broken layouts. See Change #4204.

53649 Folder IDs were shown in PIM objects attachment details

For PIM objects with attachments we did show the hyperlinks pointing to OX Drive instead of the corresponding App. To avoid confusion we did visually remove those links as they provide almost no functionality.

53474 Duplicate recipients when sending mail

When sending a mail to all appointment participants the resulting mail compose did contain duplicates of the expected recipients. This got solved by detecting and removing the currently logged in user from that list.

53437 Inconsistency for thumbnails and image preview

Certain file formats (tiff, psd, pbm) were shown as thumbnail preview while not being supported in image preview. To ensure consistency we added support for tiff and psd files to image preview.

53313 Unable to edit name used for mail on mobile

When using OX App Suite UI on a mobile browser, updates to a E-Mail addresses "personal part" at mail compose were not reflected to the selected mail address. This got solved by updating the corresponding element after the change has happened.

Patch Release 4180 (2017-06-14)

Shipped Components and Versions

  • Open-Xchange AppSuite backend 7.8.4-rev4
  • Open-Xchange AppSuite frontend 7.8.4-rev4
  • Open-Xchange EAS 7.8.4-rev4

Fixed Bugs

53900 1st (out of two) Google Mail Account does not work after adding 2nd (out of two) Google Calender Abo

When updating an OAuth account (applying a new name), the enabled scopes was accidentally reseted.This has been solved by not touching OAuth account's enabled scopes when updating its name.

53795 POP3 External account: messages retrieved are duplicated

Certain POP3 server's do not obey to advertise UIDLs with at max. 70 characters.This has been fixed by extending the "uidl" column in "pop3_storage_ids" and "pop3_storage_deleted" tables from 70 to 128 characters as some POP3 server advertise bigger UIDL values. An Updatetask will be triggered with this fix.

53690 Fields considered for sorting / categorizing contacts inconsistent

A contact's (yomi-) firstname was not taken into account during sort name generation in case no (yomi-) lastname was set.This has been solved by using combination of (yomi-) last- and firstname per default as sort name.

53689 Yomi fields not available / visible with non-Japanese language setting

Missing feature for other languages.Added new setting and feature to make yomi fields with other languages.

53688 Contacts with Katakana "yomi" fields are sorted and categorized as "other"

Only hiragana in sorting table.Extend table with katakana to solve the first part. When yomi was given with Half-width Katakana it is still not sorted correctly, this will be fixed with an upcomming patch.

53340 Appointment status of participant not updated via EAS

The list of confirmations was not part of the USM sync-state.USM syncs now the list of confirmations from the backend to solve this issue.

53233 No appropriate folder storage for tree identifier "0" and folder identifier "label"

Used dummy folder_id 'label'.This has been fixed by using 'virtual/label' now to avoid that an invalid ID is used in server requests.

Fixed Bugs

53674 Broken filenames for certain Japanese file attachments

The "name" and "filename" attributes of Content-Type were incorrectly parsed, which led to broken attachment file names when using certain encodings. This got solved.

53457 Unread counter not updating correctly

When moving a mail to the "Trash" folder, in some cases the unread counter was incorrectly updated. This has been solved by making such "move" operations more robust for the counter.

53456 Unable to parse certain broken mails

Mails with broken Content-Type headers at their MIME part could not always be rendered. We added some workarounds in order to attempt parsing and displaying such mails.

53451 Errors when importing specific CSV

Some CSV data did trigger errors during import, caused by incorrect mappings for "Marital status" and "Employee ID" and the attempt to import read-only values like "Object ID". This got solved by adjusting the mapping and skip list.

53434 Database timeouts when executing "logincounter" CLT

The "logincounter" CLT did use excessive and unoptimized queries when generating statistics. In combination with millions of data sets this could lead to database timeouts and subsequently unusable output. We enhanced that function to use chunk-wise querying and processing of such kind of data.

53368 UI does not load but also not redirect to unsupported.html for MSIE 9.0

Latest code changes make IE9 unusable.Now sending MSIE 9 users to the unsupported HTML file.


53267 Folder inconsistencies when changing a users password

Parts of the folder representation is cached and in cases where the users password got changed without terminating its session this cache was outdated and led to problems with standard folders like "Sent". This got solved by looking up those folders via mail accounts API rather than using a cache.

53249 Unable to remove POP3 accounts

In special cases where the corresponding IMAP folder of a POP3 account got manually deleted, there were issues removing the associated POP3 account. Other issues were related to the attempt of deleting the same account multiple times. Those got fixed.

53216 Slow rendering when composing mails to many recipients

In case of more than 50 recipients for a mail, the mail compose dialog became a bit unresponsive. This was caused by unnecessary requests to contact images and got solved by allowing to asynchronously load such images as well as reducing the amount of requests.

53158 Missing documentation for oAuth scope configuration

Configuration description about oAuth and related scopes got added at

53139 Google oAuth subscriptions were not assigned

In some cases the assignment of a Google oAuth account did break, usually when adding multiple accounts. In such cases the reference was made to the default Google account rather than the account associated to a subscription. This got fixed and the correct account is referenced now.

Missing check if task folder is private.Added missing check to solve this issue.

53100 Mail is not being displayed, blocking other from being displayed in INBOX

This was due to missing recovery for an unsupported character-encoding.This has been solved by handling possible unsupported character-encoding.

53095 Unable to use oAuth accounts after permission downgrade

If a scope for a oAuth account got defined (e.g. to access a external calendar) and the corresponding OX account got downgraded to lose access to calendar, accessing the oAuth account was not possible anymore. This got improved by handling unexpected absence of scope and corresponding Apps.

53087 Second Google calendar subscription does not show calendar contents

The actual OAuth account associated with a subscription has not been considered, but always the default Google OAuth account was referenced.Solution: Consider the actual OAuth account that is associated with a subscription. Info: Popup Blocker may not be active.

53023 Message with truncated subject

Subsequent base64-encoded strings are not combinable if individual values end with padding '=' character.This has been fixed by not combine padded base64-encoded values, but decode them separately.

53008 HTML content is invalid and cannot be displayed

Weird start tag segments in real-world HTML messes-up HTML parser refusing to process the content any further.Solution: Better deal with malformed start tags in real-world HTML content.

52959 Layout issue with sharing on mobile

When sharing a link on smartphone devices, the dialog was displayed in a way that the input field for recipients of the link was not shown. This has been solved by allowing to scroll that section into the viewport on small screens.

52928 Attachment not shown

In email with attachments which have different cid and id it was not possible to show all attachments.Make sure attachments do not have a cid attribute when added to a collection to solve this issue.

52798 Missing appointments in Outlook

In special cases, a list of deleted change exceptions for recurring appointments was provided by Outlook to USM, which led to an exception and subsequently incomplete sync. This got fixed by considering this case.

52797 Autoconfiguration fails for hotmail/yahoo/live domains

Thunderbird's ISPDB for auto-configuration changed.Changed default value for property "com.openexchange.mail.autoconfig.ispdb" in file '' from "" to

52764 Document conversion triggered without capability

Even though a users did not have the "document_preview" capability assigned, calls to the Documentconverter API were made. This got solved by considering the users capability before executing such requests, for example when generating thumbnail previews for mail attachments.

52756 Twitter can not be configured anymore;Case-sensitive look-up for an OAuth API: "Twitter" is not equal to "twitter"

Case-sensitive look-up for an OAuth API: "Twitter" is not equal to "twitter".Perform ignore-case look-up by OAuth API identifier to solve this issue.

52751 Creating external accounts does not work anymore

Wrong detection if a mail account action was targeted for primary mail account.Reliably check specified account identifier to determine primary account to solve this problem.

52730 Misleading indication that IMAP folder is shared

In case IMAP ACLs just for "see folder" are granted, the "this folder is shared" indicator was displayed. While technically correct this is misleading to users since no content is actually shared. The handling has been changed to avoid displaying the indicator for this kind of ACL.

52729 Missing reload when clearing Trash manually

When removing all mails within the Trash folder manually (select all, delete) instead of using the explicit function, the folder list was not reloaded. This got fixed by triggering a reload in such cases.

52727 UI/Browser blocked / stalled when dealing with huge amounts of appointments

To many operations in DOM-tree if having much appointments.This has been fixed by disabling some functionality for a large Number of appointments.

52712 Twitter stream not shown after configuration

Missing event in Keychain API led to this issue.This has been fixed by adding an additional event, so portal plugins update correctly.

52675 HTML mail not displayed at all

Some mails were not displayed because style tag does not get closed while sanitizing mail's HTML content.This has been fixed by orderly closing the style tag while sanitizing HTML content.

52633 Drag & drop of a huge picture into a HTML-Mail will cause the JVM to OOM/ up until OS swapped

Configured image limitations were not tested when checking for validity of an uploaded image.This has been solved by testing for image limitations when checking for validity of an uploaded image.

52607 Inconsistent naming of recurring appointment dialogs

When changing or editing a recurring appointment, different dialogs with different naming were displayed. This got unified and changed to shorter naming in favor of small screen devices.

52606 Show hidden files setting does not work at all

Hidden files were not displayed because filter extensions for files were never called.Invoked filter extension point to post process file list to solve this issue.

52534 Disableschema: SessiondService is used but not registered in the activator

Required SessionD service was not orderly tracked.This has been solved by properly tracking needed SessionD service.

52530 POP3 access to external account is not logged by AuditLog

The tracked instance of AuditLogService was not orderly put into utilized service registry.This has been fixed by properly putting tracked service into service registry.

52478 Duplicate registration of ObfuscatorService

Even though ObfuscatorService is implemented as a singleton, it got registered multiple times which led to error messages. Those did not affect functionality but led to higher log traffic than necessary. The problem got fixed by making sure ObfuscatorService gets registered just once.

52470 Incorrect detection of users USM capabilities

In certain cases a users capabilities to use USM and related sync implementations got incorrectly detected. We solved that by sticking to the advertised module access permissions instead of dynamically resolving it.

52435 running processes/instances after the open-xchange-documentconverter-server stop script on RHEL6

init script problems according to title / shutdown of ReaderEngine instances not reliable during DC server bundle shutdown, fixed init scripts, cleanup after migration for 7.8.2 / catching spurious exception during RE instance kill in Java bundle shut.

52433 Incomplete parsing of "mailto" handler at mails

In cases where a regular HTTP/HTTPS resource contains the subtring "mailto" like
"www.mailtool.invalid", that link was incorrectly detected as mailto: handler and mail compose got opened rather than the URL. This got solved by just looking for mailto: at the beginning of a URL.

52391 Empty Page in UI settings section after update

JS error in yell function and only a empty settings page were displayed.Made yell function more robust, so Settings do not break anymore.

52314 Unicode decoding fails for multi-line mail subjects

In case a E-Mail subject spans multiple lines where each consists of UTF-8 mail-safe base64 encoded characters, decoding partly failed and Unicode characters were displayed in a scrambled way. This has been solved by properly handling such split subjects and encoding each part independently.

52280 Read timeout log entries when using folders that were already closed

Several log messages referred to a situation where access to a IMAP folder is attempted which got closed already. We added optimizations to lower the probability of such cases and handle them correctly instead of throwing an error.

52277 Wrong log level for concurrent updates to last-login

In case two threads update a users "last login" information, a log message of level "ERROR" was logged. Since this is rather a temporary issue and can't be solved in retrospect we lowered its log level. Further optimizations made it less likely that this kind of issue would happen at all.

52238 Typo at NRFILES property at startscript

A typo at the /opt/open-xchange/sbin/open-xchange script led to a situation where custom configured "nofiles" limits where not correctly applied to the process. This has been solved by correcting the properties name and adding a log message to open-xchange-console.log in case the process fails to set this limit.

52231 open-xchange-documentconverter-jolokia needs open-xchange-documentconverter-client package to be installed

Changed required packages from open-xchange-documentconverter to open-xchange-documentconverter-server in spec file

52161 Missing mails on mobile devices when using mail categories

When using mail categories with a desktop browser and moving mails to specific categories, those mails would not be displayed at Inbox anymore when using the same account using a mobile browser. We solved this by avoiding categorization Inbox if the corresponding feature set is not available on the currently used platforms.

52157 IMAP master-auth user name provided to client

In case of specific IMAP errors related to EXPUNGE commands, a detailed error message was returned to the user, which could contain a user-name for IMAP master authentication. This was solved by removing detailed error message contents for that IMAP command.

52156 IMAP folder names shown different after update

Due to external account refactoring in 7.8.3, the "default0" prefix for "standard" IMAP folders was shown at the frontend. This got fixed by stripping that prefix in places where users would expect just the folder name.

52151 Drop zone for .eml not disappearing if a file is not dropped with firefox on Windows

Firefox does not trigger dragleave or mouseout correctly.This has been fixed by using mouseenter to remove the dropzone when the mouse enter the window without dragged files.

52123 Unable to change mail account name with certain mail configurations

If a user was changing its mail account displayname while the middleware uses a "global"
mailServerSource setting, incorrect host names were applied. As a result the displayname could not be changed. We solved this by applying the appropriate host name to avoid erroneous responses during the operation.

52119 Technical messages if HTML mail exceeds limits

If a HTML mail exceeds pre-defined limits, a rather harsh message is displayed at the frontend. This got polished in order to show a user friendly representation.

52114 Empty page printed by browser in thread view

Single mails are printed correctly when using native browser printing (CTRL+p) but mail threads were not printed. This got fixed by handling mail threads in a more compatible way and allowing native functions to get their relevant content.

52107 Inconsistency in naming order for external accounts

When changing the account name syntax of an external mail account, this change is not reflected to mail lists when reading mail sent and received by the same user. This got fixed by honoring a naming scheme which uses commas to separate last and firstname.

52104 Untraceable database timeouts during share cleanup

Once the PeriodicCleaner task for shares was executed, potential SQL errors could not be traced since the related schema name was unknown. To allow further debugging we addedcom.openexchange.database.schema as parameter for this cleanup run. It will highlight which database schema triggered timeouts or other errors.

52101 'Folder "9" is not visible to user "X" in context "YY"

Caused by the changes for favorite folders, where favorite folders for every module were added to the collection pool. The favorite folder for drive has the parent with id "9". When the UI is refreshed, all parents of all folders are listed. That causes every refresh to request the folder with id "9".This has been fixed by only adding favorite folders for modules with granted permission.

52100 Permission checks avoid changing corrupt users signatures

In case a users signature contains a faulty "createdby" header on file-level, subsequent changes to that signature were rejected based on a permission evaluation. In order to accept inconsistent data within in the system, the permission check has been removed.

52095 Missing private appointments in shared folders via CalDAV

When sharing calendar folders and accessing them via CalDAV, appointments marked as "private" were not correctly synced. The same use-case works fine when using the HTTP API. This got fixed for CalDAV by considering this kind of appointment when creating responses.

52067 Enter a text in the Search bar. Click on the close option but still the pop up with the text is not closed

Now clear and close dropdown on cancel to solve this issue.

52022 Incorrect App launched from external accounts page

When using the hyperlink for a external storage account at the Settings-Accounts page, no or the wrong App is launched. This has been corrected and a fallback to Drive was added.

52013 Enhancements to IMAP host detection and logging

To allow better debugging and monitoring of interaction between OX App Suite and IMAP backends, a new parameter was added to parse the IMAP backends "greeting" and provide it as part of the OX App Suite log. This behavior is configurable and described within release notes. When rolling out this Patch Release.

51967 Missing distribution lists in Outlook

When syncing Outlook using USM, certain amounts and combinations of contacts and distribution lists could lead to a situation where only a subset of contacts but not all distribution lists got synced. This has been solved by sorting the type of object (contact, distribution list) prior to performing the sync operation. This way the kind of objects retrieved at the client side stays consistent in case the total amount of objects exceeds the chunk size for one sync operation.

51960 Incorrect font for mail attachment on mobile

When using OX App Suite UI on a smartphone, the "Attachments" link within mail compose has been shown with incorrect font and color. This got fixed by applying proper mobile styles to this link.

51918 Calendar conflicts with UTC+12 timezones

During conflict detection, the floating time-span of full-day appointments was calculated using the servers timezone (usually UTC) while other appointments used the timezone configured by the user. In cases where a large offset to UTC is present, there has been a 50/50 chance that appointments would conflict with full-day appointments at the previous or next day. We're now calculating both values using the users specific timezone for conflict handling. This should bring down the probability of incorrect conflicts considerably.

51910 Huge amount of threads stops OX

Did some improvements to avoid a crashing OX. Utilize a user-scoped lock mechanism to avoid having a global lock that might affect unrelated threads unnecessarily. Avoid duplicate remote session look-up.

51859 Changed API behavior leads to issues with file uploads

An earlier bugfix introduced a significant change to HTTP API behavior, any change to the MIME-Type parameter has been rejected as a result. While OX clients were unaffected, this led to an incompatibility with third-party clients when using the "infostore" API for uploading and modifying files. We reduced the scope of the change to block MIME-Types that start with "multipart" instead, this should not affect the vast majority of use-cases for this API.

51839 Certain serious (non UCE/UBE) HTML mail is not displayed

Too greedy check for possibly malicious content led to this issue.This has been solved by allowing properly parsed start tag.

51772 Unable to modify users own data

In cases where the contact associated to the user account was created by the "oxadmin" account rather than the user itself, the user was unable to change its own contact data. Such situations may arise in specific provisioning implementations. Changing the contacts data is now possible again by correcting the mechanism to look up the oxadmin account as potential creator for the own contact.

51755 Long-running script warnings when sending mail to huge recipient list

When composing a mail to a list of several hundreds of recipients, browser warnings about unresponsive scripts occurred when trying to parse and tokenize the recipient list. The handling has been improved by 2-3x to allow a larger number of recipients.

51727 Mail icon stills appears in UI even though mail is not enabled

Caused by missing capability check for disabling and hiding.This has been fixed by adding the missing check.

51700 Guided tours showing for users even though the package was not installed

Document tours are contained in documents-ui package, existence of standard tours package was not checked there.This has been solved by adding check for existence of standard tours package, do not show tours automatically if missing, hide settings menu entry.

51610 Desktop notifications are not shown for negative timezone offsets

When configuring a negative timezone offset (e.g. UTC-5), desktop notifications would not be shown since the timestamp of newly received mails was checked against UTC rather than the users timezone.

51602 Incorrect encoding when using IMAP "plain" authentication

In case mailbox login names allow multi-byte Unicode characters, the login process would fail when using OX App Suite. This has been solved by applying the correct charset when performing the login procedure for mailboxes.

indexing mismatch between the DOM nodes representing the file items and the model entries holding the file data.This has been solved by fixing the sort method.

51572 Moving files with and without description not working in drive

App Suite UI just redid the same operation.Solution: App Suite UI checks which files caused conflicts and only tries to redo those.

51570 Only one warning for copy multiple files with description in drive

Multiple response was not fully processed.This has been fixed by processing full array.

51569 Primary mail address and aliases cannot be changed at the same time if the old primary mail address should be an alias

During the createuser command an alias for the primary mail account is already added. This alias is equal to the upper case notation used in the create command. The change command now tries to add the same alias but with only lower case letters. This isn't recognized and therefore the middleware tries to insert this alias to the db again which results in the duplicate entry error.Solution: Do a case independent check when comparing the old with the new aliases.

51548 Moving files which already exist result in duplicate files with Google Drive

There was no name check performed for the move operations.This has been fixed by adding the name check to the move operation.

51468 Failing to parse pre-auth from configuration

Inappropriate invocation of 'MailConfig.doCustomParsing()' lets Zimbra MAL connector fail to perform its own parsing of access information.Solution: Do call 'MailConfig.doCustomParsing()' regardless of passed parameters.

51462 Full-day appointments could not be converted with Lightning

When using Thunderbird/Lightning and CalDAV of OX App Suite, full-day appointments could not be converted back to normal appointments using the CalDAV client. The reason for this was a client-specific CalDAV header used to indicate full-day appointments which caused issues with Lightning. We removed this header if the associated user-agent does not expect it.

51399 Repeated mail sending when using Outlook

In case a backend error did occur, like downtime of the mail storage, there could be situations where Outlook clients using USM get into a sending-loop, resulting to duplicated E-Mail. Those kind of errors are now handled by the USM API in accordance to the OX App Suite middleware error code.

51388 If email is disabled, OX Docs tour should not show "Send as email" icon

Guided tour for OX Text does not display info about mail,if mail is not available

51368 Bursts of WARN Messages: filemanagement.internal.ManagedFileManagementImpl ..Temporary file could not be deleted about 800-1000/day

Delete attempt does not check whether file is non-existing.This has been fixed by properly checking if attempt is made to delete a non-existing file changed logging appropriately.

51357 No participants can be added in Scheduling with IE11 after an update

IE has problems with flexbox styles.This has been fixed by changing styles to fix the problem.

51356 Missing support for custom login sources for onboarding

When using the "onboarding wizard" while having a custom login implementation running, some configuration templates could not be properly created since access to the correct credentials (e.g. mail address, login name) is not possible. This has been solved by offering the ability to integrate custom login sources.

51313 Errors when adding invitations to calendar while tasks are disabled

There has been a dependency between the calendar and tasks App with regards to handling iCal files, which led to a situation that appointments could not be imported if tasks are disabled. This dependency has been relaxed to allow cases where either App is disabled.

51263 Missing function returned in case requested files could not be found

A earlier fix changed the response content when requesting a frontend related file. Instead of a function and a error message, just a error message was returned. As a result the web frontend could get stuck in case a file was not found. This has been solved by providing a similar response than earlier, just with obfuscated payload.

51222 Big text file load endless with the UI

The client request didn't get a response.With these changes the Viewer displays an error message if the file is too big to be loaded.

51207 Error message shown if "default app" setting is empty

In cases where a users configuration was damaged and the default App "none" has been selected, subsequent logins led to error messages. We're now falling back to the global default App if the provided App cannot be found.

51101 showruntimestats -a errors: No such cache: OXIMAPConCache

OXIMAPConCache is an obsolete JCS cache. The StatisticTools was querying the JCSCacheInformation for that particular non existing cache. The same applies for MailConnectionCache and SessionCache.This has been solved by removing the obsolete calls and corrected the error message.

51091 Upload to external filestorage account folder does not abort if overquota and fails

Missing error handling for overquota in multiple file upload.This has been solved by checking error FLS-0024 and stop queue if this error appears. Also check for rate limit error. If one of those errors appear, the upload queue stops and removes all files from the queue.

51075 Missing translation for upload progress bar

When uploading files as Mail attachment or Drive object, the corresponding progress bar offered a "Cancel" button that was not translated.

51074 Encoding issues with passwords

In case certain operating systems got configured incorrectly, specifically RHEL6 and SLES11, usage of the open-xchange-passwordchange-script plugin could lead to incorrectly encoded passwords passed over to a script. This has been solved by adding an optional parameter as described by Change #4022 to allow base64 encoded transfer. Additionally, unexpected encoding configurations will get logged to open-xchange-console.log to alert operators about potential follow-up issues.

51053 Appointment invitations get duplicated by adding attachments

Deactivated Notification pool combined with multiple uploads of attachments result in a single notification mail for each attachment.Solution: Keep track of a batch of attachment uploads during the whole stack.

51018 Munin warning updating config_ox_java_heap

Non-existing mbean raised an error.This has been fixed by removing mbean.

51017 Munin error updating last-error in ox_grizzly_TCPNIOTransport

Last error value was not a simple signed integer.Check for "N/A", will return 0 instead of "N/A" with this fix and will only fix the problem for ox_grizzly_TCPNIOTransport.

50997 Searching inside of sent mail folder always shows senders name in results column

This has been solved by adding special handling in find App.

50991 Exception generating IMAP URI

A possible scheme/port information in "com.openexchange.mail.mailServer" or"com.openexchange.mail.transportServer" property was not properly handled.This has been solved by using a structured object for the global mail/transport server configuration setting to also apply protocol, port, etc. (if specified).

50987 AutoStart is not working with io.ox/settings or portal

Settings is not a favorite App and is therefore ignored as autolaunch.This has been solved by adding a special case for settings. Settings will not appear in the dropdown but can be set by the provider as default autoStart App.

50982 External Cloud Storage: number of Items in folder not displayed - '0' all the time

Some file storage implementations are not returning a file count.With this fix the file count is not displayed if the external storage returns no value for file count.

50965 Restore compose application pop up not loading with 7.8.3 upgrade

Introduced new value for ox.serverConfig.persistence: "always". Only works with adjustment in custom bundles.

50964 Enable Notification sounds - Play sound on incoming mail not working

Settings pane for message sound was displayed when no websocket support was available.This has been solved by adding missing capability check.

50951 In a 'Drive with Documents' environment drive offers to send by mail

OXGuard extends "send as mail" ext.point, but the capabilities are NOT extended – now with manual check for capabilities.

50947 OX Documents Portals don't work for users without default folders

The implementation now checks the default template folder and use the user's default folder as a fallback.

50939 Missing context menu for conversation thread view

When using conversation (thread) view, the context menu was not added for each individual mail but for the whole thread and the first mail. This makes it hard to handle individual mails and got solved.

50918 Timezone issues with task start/due dates on negative timezone offsets

When defining a start or due date for tasks while using a negative UTC offset, the selected date would be reported incorrectly. This has been solved by adjusting the full-day handling for tasks to the calendar implementation which uses UTC.

50868 Missing translation for external accounts

The "My accounts" page at "Settings" did contain untranslated strings for external account names, this got solved by making use of existing translation strings.

50837 Birthday on 1.1.1970 not displayed

Timestamp for 1.1.1970 were interpreted as timestamp 0. Adjusted calculation from Birth Dates to solve this issue.

50835 Report doesn't terminate if contexts are broken

In case of a context that never existed on the system, a lookup for all contexts in the same schema lead to endless attempts to get those contexts.This has been fixed by adding the initial context to context list, if the database returns no values for the given context id. Add potential errors to output report.

50804 Attached vCards could not be removed again

When adding own contact information to a Mail as vCard, that virtual attachment could not be removed afterwards. This was caused by an API change which is now reflected to mail compose.

50798 Renaming a root level folder which contains a Favorite Folder will lead to "Mailfolder not found on IMAP Server"

Missing checks if parent folders get renamed or removed.This has been solved by looking for rename or removal of parent folders. On rename: anticipate changed path and keep folder. On remove: immediately remove affected favorites. This doesn't work if triggered by another client.

50738 Not possible to import multiple mappings with CSV file

"Addmapping" value was not split by comma when supplying multiple login mappings via csv file at create context.Now split multiple login mappings by comma during context creation from CSV file to solve this issue.

50714 OXtender synchronization fails with Couldn't determine extra fields in object with errors

The ical analysis of an external invitation delivers an JSON object "users" without sub fields, especially without confirmation. This was unexpected by USM and produced an error, which led to a general sync error with OLOX.Now the missing confirmation is accepted and initialized by USM with 0.

50706 OX APP Creates too many IMAP connections and not closing them

Unnecessary global lock that leads to stacking up threads.This has been solved by removing unnecessary global lock from'' class for improved throughput.

50693 Content pane folder name not refreshed when renamed on external storage

Error handling is now done inside the apps. If errors with external storages (or other folder errors) appear and that folder is currently selected, the App will change to the default folder and reload the parent folder.

It was possible to share folders of an external storage account as link to other internal users. Since those accounts are per-account, that link would not work though. Therefor we removed the option to send a link to such folders to other internal users.

50689 Possible to lock files in external storages when not supported

The 'locks' capability was not correct for some external storages.Changed behavior: The file lock feature is disabled for every external storage. Lock does only work in the internal ox fileStore now.

50674 Deleting 2 Users at a time via SOAP results in a database deadlock

Possible database deadlock on concurrent delete attempts for users in the same context.Solution: Acquire a lock on user deletion to enforce queuing of concurrent delete calls.

50627 Mail content not displayed

Malformed conditional comment (CC) causes to greedy detection of such a CC pattern in HTML content during sanitizing.This has been fixed by dealing with malformed conditional comments.

50621 OX crashed - one node/JVM permanently on GC/100% CPU - after creating an heap dump error looked different but OX still does not react

Really weird HTML content inside a mail containing over 700 nested body start tag segments renders the routine running mad that tries to replace body tags with div tags for embedded display inside App Suite UI.This has been fixed by avoiding excessive replacements of body tags inside such a really weird HTML content.

50598 Missing warnings for account failures at unified mail

In case a external mail account cannot be used (e.g. because the password changed), there has not been a notification to the user in order to resolve the situation. This has been changed to provide warning messages when trying to accessing a unavailable account.

50574 Expiry dates for shares cannot be changed directly

When sharing a object with expiry date, that expiry date was set to "one month" when editing the share afterwards. We solved that by no longer applying the default value when editing a share.

50570 Not possible to change name in email settings if global configuration is used

MailConfig values were overwritten with wrong values.This has been fixed by preventing overwriting in specific situations.

50527 MySQL databases refuses connection because of Too Many connections from single groupware servers

Incrementing use-count for a lot of contacts associated with a certain E-Mail address causes too many INSERT statements to be issued, that do flood the MySQL service.This has been solved by accumulating use-count incrementation through a batch statement and limit the number of updated contacts that are associated with the same address. That limit is configurable through property "com.openexchange.contactcollector.searchLimit" and defaults to "5".

50519 Not possible to find group in calendar permissions dialog

Groups where not drawn due to a limit.Now applying limit by result type so groups are drawn.

50518 Email module - Burger Menu - Create filter rule is not responding

Due to the deactivation of the "address" mailfilter the default values were not available.This has been fixed by introducing a fall-back to the former "header" filter if "address" is not available.

50495 Adjust “hover” color in OX Text and OX Spreadsheet.

Use the actual hover fade value as defined in current UI theme.

50478 Impossible to add two or more different Gmail accounts

Initial assumption to re-use OAuth credentials was wrong.Now OAuth credentials are not re-use when adding mail accounts.

50461 HTTPClientActivator never calls Services#setServiceRegistry

Services class was not initialized.This has been solved by properly initialize the Services class.

50414 Birthdays in the portal widget/side-popup are sometimes a day off

Birthday calculation was slightly different in both views and apart from that even not correct for all cases.This has been solved by using the same code for both views and also using a correct approach.

50412 Edit incorrect email address in to or cc generates duplicate entries and phantom entries

Collection and token field state gets messed up cause models ‘token’ attribute get updated within the ‘tokenfield:createtoken’ handler.This has been fixed by redrawing Tokens only when the display name has changed.

50407 Missing hints for incorrect server startup

In case syntax errors are present at YAML-style configuration files, the middleware did start up partly but apparently was not logging this situation clear enough for some operators. We improved error messages that are thrown once this happens to make it more clear.

50404 If Sharing is disabled, the sharing button is still available in OX Documents

linked caps and implemented "hide disabled elements" feature

50381 Further E-Mail fields not shown in case primary mail is missing

If multiple E-Mail addresses are stored for a contact but not "E-Mail 1" and neither Company nor Position are available a blank second line at the contacts list was displayed. This has been adjusted to fall back to "E-Mail 2" and "E-Mail 3" in case "E-Mail 1" is unavailable.

50342 Calendar colors get lost on printouts

No custom label colors applied to template.This has been solved by passing colorLabel identifier to html output.

50328 Incorrect cursor placement for plain-text signatures

When using default plain-text signatures and navigating with the TAB key, the cursor would be set at the end of the signature. This has been solved in a way that the cursor will be set to the beginning of the message.

50307 Incorrect translation for maximum upload size

When uploading several files which combined size exceed the maximum upload size, the related error message was related to the last file which got added. However, in such cases the error is related to the combined file size, therefor the wording has been adjusted.

50303 No error message regarding "No such snippet found for identifier:" when filestore not available on login

This was caused by a missing hint that a file associated with a snippet/signature is (temporary) not available.Restored logging in case the file associated with a snippet/signature is (temporary) not available: "Missing file for snippet 1 for user X in context ctx_ID. Maybe file storage is (temporary) not available."

50258 Categories - select all in one of the tabs - info message that no all mails all selected is missing

Added new message for "select all" in tabbed inbox, some translation will be provided with the next patch.

50244 Task title truncated / does not use all available space

Media queries were not flexible enough.This has been solved by using flex layout to use available space better (private and due time appear in this row too if set).

50232 Renaming a folder which is present in Favorites removes it from Favorites

The folder ID changes, therefore the folder was lost on page reload.This has been fixed by listening to ID changes and update and store favorites.

50230 Connection losses to Logstash go unnoticed

In case connection to a Logstash server gets interrupted, log messages will be lost. We introduced a buffer for such messages that gets filled in case the connection is temporarily unavailable.

50213 Edit draft loads endlessly

Recognizing HTML input was not working correctly in all cases.Now wrapping content with div.../div in those cases to solve this issue.

50176 Dragging an email from desktop to mail-category tab is not working

No Handling for Drag & Drop in mail-categories.Added the missing Handling, first the mail is imported to the inbox and then moved to the category.

50135 Help not context sensitive in settings

The app did not contain any information about contextual help.This has been solved by showing context sensitive help in settings. External apps can also register their help pages on the extension point 'io.ox/settings/help/mapping' in the function list.

50093 Date or size where not shown as column headers for mail attachment view

When sorting mail attachments by Size or Date, the corresponding column header was not show, this is now the case.

Was caused by missing capability check for version comments.This has been fixed by adding capability check for version comments.

50041 Moving files with description to external storage not working

Missing translations were added.

50040 Content pane not refreshed

After deleting a folder in a external storage account the view was not updated.With this fix the view is updated after deleting a folder.

50039 Problem with folder rename of external storage providers

Dropbox identifies the folder through the path. New Files create all folders in their path by default. This is a special Dropbox behavior.This has been solved by checking for folder existence before storing a file and return default "folder does not exist exception".

50016 When composing an email, the signatures do not get refreshed, when adding initial/new one

This has been fixed by using standard listener.

49989 Onboarding Wizard Connect Device Tile does not fit into frame

Max-width were applied on whole container.This has solved by applying max-width for description only.

49979 Guest users don't get deleted

Guest user deletion triggers push listener removal for guests even if they might not have any push listener registered.Solution: Consider webmail permission before removing push listeners within the user deletion process.

49864 Full-day appointment will be displayed as a regular 24h appointment on Android

Specific clients rely on a certain order of the EAS protocol elements. AllDayEvent shall be sent after StartTime,EndTime. Microsoft Exchange Server for example does this.Sending AllDayEvent after StartTime,EndTime.

49781 Email list: email address displayed instead of display name when DISPLAYFROM is enabled

Now show display name if DISPLAYFROM is set.

49731 Missing event data when deleting an appointment after accepting it

The Appointment object at the deleteDateFromNotoficationQueue event was missing some typically unused data in cases where a participant deletes the appointment after accepting it. To allow compatibility with certain calendaring implementations, we now add a full Appointment object to the queue in such cases.

49236 Huge amount of Mail folder could not be found on mail server messages for non-existing folders

The message for "Mail folder could not be found on mail server" were known, actually by design, but not expected to happen that often.The fix just excludes the inbox from the obfuscation, to reduce the amount of error messages.

49099 sporadic crashes in UNO bridge when loading CSV files via UNO with format string given via FilterOptions string property

setting field delimter and text separators in RE SC code instead via UNO on DC server side

49083 E-Mail-Folder Action 'delete all messages' ignores OVERQUOTA

Copy command was able to run into over-quota.This has been fixed by using move operation for clear folder command in case move operation is supported by IMAP server.

48361 Login not possible if folder limit is reached

Adjusted login- and error-handling to solve this issue.Special error code "MSG-0113" in case creation of default/standard folders fails with an "over quota" error was added. This Error will be displayed after login to the end-user.

47616 Interval setting in calendar not used

When setting a interval for calendar time scales, that interval was applied for time pickers and drag-lasso. Now this interval is also used for the calendar views time scale.

47229 Mail folder menu contains "Sharing" and "Permissions"

Capabilities of mail folders were incorrectly checked in case the mail system did not support permissions. As a result the context menu contained permission related actions which were not working as expected. We added a explicit check for environment where permission handling of own mailbox folders is disabled.

40632 Collected addresses does not work for users from the same context

In cases where multiple users are provisioned to the same context with the Global Address Book disabled, automatic contact collection of addresses that are present at the Global Address Book has not been performed. We changed the behavior to consider cases where the Global Address Book exists but cannot be accessed.
