BM-23996: Fixes: Incorrect month in an event's recurrence in an ICS export.
BM-24039: Fixes: Interface for the pending invitation counter when the user has a large number of shared calendars.
The "Pending Invitations" badge now correctly takes into account shared calendars with write access—including those shared through a group—to allow a delegate to respond to invitations on behalf of the owner.
BM-22982: Fixes: Empty blocks appear when printing a PDF of a shared calendar with "view only" permissions.
BM-24075: Fixes: A user with permissions on a shared mailbox does not receive event invitations sent to that mailbox.
The day of the week for a weekly recurrence rule is now displayed correctly, regardless of the language configured on the server.
BM-24039: Fix: A CalDAV request to the calendar root no longer fails entirely due to a single obsolete subscription or one whose owner has been suspended; only that resource is now ignored.
BM-23941: Performance improvement that prevents the generation of the offline address book (OAB) or the loading of contact records from overloading the server and slowing down Outlook/EWS clients.
BM-23623: Fixes: Duplicate emails after deletion in Outlook 2019.
BM-24025: Fixes: An event whose attachment has been moved to file storage is not properly resynchronized in the organizer's Outlook.
BM-24113: Fixes: When an administrator confirms a resource reservation, a notification is sent indicating that the reservation has been canceled.
BM-24129: Fixes: When an import error occurs—for example, while creating a shared mailbox—the AD import task incorrectly reports that it was successful.
An Active Directory import no longer incorrectly blocks the license verification process for an administrator who does not have the subscription management role.
BM-23048: Fix/Improvement: Scheduled jobs (e.g., (backups) are no longer sent from the internal technical address no-reply@global.virt, which is often flagged as spam; a dedicated sending address can now be configured.
BM-23878: Fixes: Issue with the "Log in as" link in the administration console.
BM-24134: Fix: A reindexing scheduled job before a domain switches to the new alias mode (ring) is now properly ignored instead of running with outdated logic.
BM-24162: Fixes: Calendar restoration fails for events whose tag does not yet appear in the session.
BM-23953: Fixes: After an upgrade from version 4 to 5, the backup task reports that it has completed successfully even though some copy tasks have failed.
BM-24100: Fixes: Emails lost during multiple redirects.
BM-24138: Fixes: Some emails were marked as sent even though they had temporarily failed (e.g., server unreachable).
Fix: Emails are now held in the queue, and the server automatically retries after a certain amount of time.
A clone of an installation no longer gets stuck indefinitely while waiting for certain keys—generated locally on the cloned installation—to be replicated.
Tracking the progress of a clone is now organized and manageable, with a dedicated command to monitor its progress in real time and to resume or skip a failed recording.
The restoration of the directory, email bodies, and the message queue is now parallelized and performed in batches, resulting in faster clones.
Converting a shared mailbox now correctly preserves its data location, quota, and routing when cloned.
A clone no longer fails when a folder tree is temporarily deleted and then recreated during a mailbox-to-shared mailbox conversion.
Some unrecognized iCalendar settings (e.g., (icon links added by Thunderbird) would lose their filenames when saved again, which could corrupt subsequent attachments for the same event.
