What's New


Zimbra 9.0.0 is now fully supported on RHEL 8 (GA)

Download the latest RHEL 8 binaries from https://www.zimbra.com/downloads


Common

  • Event details open in a new tab when users create an event, allowing them to navigate and use the Modern Web App without losing unsaved event details information.

Mail

  • Users now have an option to write emails in plain-text.
  • When a user delegates access to another user with "Save a copy of sent messages to my Sent folder" setting enabled, then mails sent by the delegate are saved in delegator's sent folder.
  • After selecting a message, users can create a quick filter from the email context menu.
  • In message and invitation forwards and replies, the header information of the original message is now duplicated in the body of the new message. This gives new recipients a view of who the original message or invitation was sent to, who sent it, and when it was sent.
  • Users may observe improved performance when using composer for creating messages and managing drats.

Contacts

  • Deleted Contacts has been renamed to Trash, and the right-click context menu for Trash now has the option Empty Trash. These changes are present in all supported languages.
  • Users can assign a tag, or delete any existing tags for single/multiple contacts.

Calendar

  • Every event invitation now includes a copy of the event information in the email body so that invitees using third-party clients can see the event info without opening the .ics attachment. Previously, only events with content in the Notes field had an email body in the invitation.

Briefcase

  • Users can now share folders with other internal users. All the permissions are similar to Mail folder sharing.
  • Folder Navigation support has been added. Users can now create, rename, delete, and move folders/subfolders.
  • For Briefcase, file moves can be performed via "drag & drop".

Search

  • Users will have more options in Advance Search :- Unread mails, Starred mails, Status, Tag.
  • Enhanced Advanced Search for email. Users will now have options to:
    • Search in subject or body or both.
    • Add Date options -- Send before, Send after, Send on.

Settings

  • Improvements in Persona management in Settings > Accounts. Selecting an existing Persona opens it in an edit mode where users can modify or delete the Persona.
  • We've simplified the user settings for forwarding email, under Settings > Accounts > {DEFAULT} > Access your email elsewhere.

Web UX - Classic

  • We have added a Zimlet for the Classic Web App to notify users of an unsupported browser Internet Explorer that it is , and encourage them to upgrade. It is recommended that this Zimlet be enabled and mandatory for all users in order to reduce support calls.
  • The sign-in screen, sign-in Help modal, "Forgot Password" workflow, Client Preferences, and Profile menu are now localized in all supported languages.

ZCO

  • Inline images in meeting notes now sync to Zimbra and are encoded to appear as inline images in the Zimbra Web Apps, instead of being attachments.

Zimbra Connect

  • Zimbra Connect has added UI support for: Portuguese, German, Italian, Spanish, Simplified Chinese, Indonesian, Thai, and Hindi languages.

Zimbra Drive

  • Zimbra Drive has added UI support for: Portuguese, German, Italian, Spanish, Simplified Chinese, Indonesian, Thai, and Hindi languages.

Fixed Issues

Platform

  • Zimbra Collaboration on RHEL 8, Monitor > Server Status now no longer shows the running services as stopped.
  • + Fixed Null pointer exception encountered while sending mail using data source created without an email address
  • + Fixed permission denied error while sending email to DL from user having SendAs rights
  • + Note: Fixed above two issues in updated Patch version today dated July 03, 2020 which were reported on first version of 9.0.0 Patch 4

Web UX - Modern

  • Fixed a problem that caused email address resolution to unexpectedly trigger on some non-English keyboard layouts.
  • Emails that contained HTML <form> tags were not being displayed, as a security precaution. These messages are now shown, with any potentially dangerous form actions suppressed by the Zimbra server's OWASP Sanitizer.

ZCO

  • Fixed an internationalization problem with the mailbox rules "Run Now" feature, that caused an error message if the language was set using a Language Interface pack instead of the language options in the advanced settings.
  • Signatures containing external images (URL references) had those images added as attachments to messages. Such messages would appear in "has:attachment" searches when the only attachment was the signature image.
    Users now have an advanced option, "Signature pictures sent as attachments" to control this behavior. When disabled, the image URL will be used without an additional attachment, thereby reducing the size of the message.

Zimbra Connect

  • Connect now honors time zone settings when logging in from the Modern Web App.
  • When a meeting host has left a meeting and attempts to start another one, they are now notified if their previous call still has attendees on line. The host may choose to return to that call, or terminate it to start their new one.
  • Users can now choose if they want to activate the webcam, the microphone, or both before joining a meeting.
    • Users are no longer required to have both a webcam and a microphone to start an audio call.
  • Connect now has a notification built in the Modern Web App. It sounds an alert for 10 seconds when a user is invited to join a group/space/channel video call.
  • Added GAL searches when an internal user is sending invitations for an existing instant meeting.
  • User interactions have been improved. Users can now silence other participants, disable other participants' video. Disabled streams appear with an icon.
  • Graphical restyling: The look of conversations is more clear, space is better used, and users can see more messages without scrolling.
  • Improved user experience when the host leaves an Instant Meeting.
  • Minichat size is increased and the header is rebuilt.
  • Added translations for Portuguese, French, German, Italian, Spanish, Dutch locale.
  • Now pictures can be set as an icon in Connect groups to identify them more easily.
    • Profile pictures are always centered and not tiled.

Zimbra Docs

  • Editing documents from the briefcase if the default domain is not set has been fixed.
  • Docs is now able to open a specific version of the file from Drive.

Zimbra Drive

  • Users can now attach files from Zimbra drive while using the Modern Web App as well. Earlier, this option was available only in the classic web app.
  • Added translations for
    • Portuguese
    • French
    • German
    • Italian
    • Spanish
    • Dutch
    • Japanese
    • Simplified Chinese
    • Indonesian
    • Thai
    • Hindi
      NOTE: Translations are still in beta. Admin Console translations are planned for the next release.
  • Drive now implements file versions handling.
  • Save to drive feature in the Modern Web App allows email attachments to be saved directly into drive.
  • Users can now add multiple files from their drive to their emails. Earlier, they had to add each file individually.
  • If a user tries to create a new share to an external email address in Drive, now a popup with an error message is shown instead of the full stack trace.
  • Fixed a menu icon which was missing from Edit with docs menu in drive.
  • Improved scrollbar management when enabling/disabling the info panel in drive.
  • Fixed an issue that displayed only the first 30 results when searching drive items while the browser zoom setting is close to 70%.

HSM

  • The doCheckBlobs command resets the list of checked files after each mailbox check, to reduce memory usage.
  • Administrators can now choose a target volume when using the command mailboxmove to move mail and drive items.
  • Continue with another policy when an HSM policy’s destination volume has reached the space threshold.
  • doMoveBlobs now checks if a secondary store is set before executing the doMoveBlobs operation and returns the error Secondary store not set when not set.
  • Dumpster items during mailbox move operations are now verified for missing blobs.
  • Fixed a description mismatch for s3 bucket region between command line and web admin interface.
  • In doCheckBlobs operations, setting check_digests and fix_incorrect_compressed_digests to true verifies if a blob has been compressed twice and fixes that.
  • Improved doCheckBlobs command output so that an account is listed only once.

NG Backup

  • Now the external restore can restore all the contacts groups in the accounts even if the restore operation is interrupted before all the accounts have been scanned.
  • Smart Scan now performs backup and coherency checks to determine if a missing blob is found in the backup while HSM service is disabled.
  • The command zxsuite backup doRestoreBlobs now checks if the volume id is valid and returns an error if the check fails.
  • Added account id reference in undelete log lines in mailbox.log to simplify the debug operations.
  • Allow only external restore operations to recover accounts that do not belong to any domain present on this host.
  • Improved doCoherencyCheck memory management, so it keeps only the exception message instead of the complete stack trace.

NG Mobile

  • Implemented anti-DOS service for mobile devices. Number of requests is counted within a time window, and if exceeded device is jailed for a specified duration.
  • The user’s last login in LDAP is now correctly set.
  • Invalid values of WeekOfMonth field are now handled in Exchange ActiveSync synchronization of calendar appointments.
  • Improved flag management to remove risk of conflict between web client and EAS client mail flag updates.

  • Users encounter a restore issue that terminates a restore operation before recovering conversations if users send attachments in any of the conversations.

Zimbra Drive

  • PDF files do not have Open as one of the options in context menu.

Zimbra Connect

  • Connect localisation works only after refreshing browser when the using Modern Web App.
