EXCHANGE NOTICE 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. |
