Some users' calendars may not be synced with delegates' calendars in Exchange Online
Service Degradation

User impact: Users' calendars may not be synced with delegates' calendars in Exchange Online.
More info: While the service provider works towards resolution, affected delegates can mitigate impact by navigating in the Outlook desktop client to File > Account Settings > their delegate account > More Settings > Advanced and turning off the "Turn on shared calendar improvements" setting. This will revert those delegates to using a shared calendar model utilizing Messaging API (MAPI) components to bypass impact.

Current status: The service provider received reports of an issue in which some users' calendars may not be synced with delegates' calendars in Exchange Online. Their investigation determined that a recent deployment contained a code issue that introduced a compatibility problem that's preventing calendars from syncing as expected. They've reverted the offending deployment and identified an increase in backlog data that's continuously preventing the calendars from syncing. They're further investigating the source of the increase in backlog to identify an efficient remediation plan to restore service functionality.
Root cause: A recent deployment contained a code issue that introduced a compatibility problem that's preventing calendars from syncing as expected. https://status.dal.ca/service.php?Service=6 2025-02-21 08:52:57 EXCHANGE NOTICE

User impact: Users' Microsoft Teams desktop client intermittently crashes.
More info: Users may see a "We've run into an issue" error message. Affected users who have access to the Microsoft Teams web app can leverage this as a workaround.
Current status: We're finalizing the deployment of the fix throughout the affected environment, and we've confirmed that users on versions of the Microsoft Teams client 24120100221 or higher no longer encounter impact. We're anticipating the deployment should be fully complete by our next scheduled update, although some users may receive the fix prior to this time as the updated build saturates throughout the affected environment. After the deployment has completed, users encountering residual impact may need to restart their clients to receive the updated build.
Scope of impact: Your organization is affected by this event, and a limited number of users have their Microsoft Teams desktop client crash intermittently.
