M365 Exchange Online: Calendar items intermittently missing/not updating
Update - The M365 Admin Team, in collaboration with departmental IT teams, affected users, and Microsoft’s product group, continues to investigate this issue at the highest priority. Microsoft engineers have identified that a background calendar synchronization process is not functioning as expected and have engaged the development team for further review. Ongoing analysis and information sharing are helping narrow down contributing factors and improve service stability.

While the investigation continues, some observed behaviours may include, but are not limited to:
- Calendar invitations are taking several hours to sync or update.
- Some meeting invites are arriving without the “Accept on behalf of” option, limiting delegate functionality.
- In isolated cases, meetings are accepted on behalf of an executive, later disappearing from the executive’s calendar.
- Duplicate meeting invites are being generated automatically, including one marked as Draft and another showing “No location added” despite a meeting link being present.

Teams will continue gathering reports and working closely with Microsoft to restore consistent behaviour and prevent recurrence.
Further updates and an ETA will be provided as soon as they become available.
Jan 29, 2026 - 15:30 EST
Update - The M365 team is continuing to work closely with Microsoft engineers to address the Exchange Online calendar issue. At this time, delegates may experience an approximately one-hour delay between accepting a meeting invite and seeing the acceptance reflected on the calendar.
Jan 26, 2026 - 13:24 EST
Update - We are actively working with Microsoft Premier Support to identify the cause and restore normal service.

In the meantime, please advise users that calendar updates may be delayed; however, the meeting should still appear within 1-3 hours.
Jan 22, 2026 - 14:26 EST
Identified - The M365 team is investigating reports of Exchange Online issues affecting calendar functionality (missing or unsynced delegate/resource calendars, invites not appearing after acceptance, and shared mailbox calendar events disappearing).
Some users may also see sent messages not appearing in Sent Items.
We are actively working with Microsoft Premier Support to identify the cause and restore normal service.

Workaround: Until this is resolved, delegates may manually enter meeting details into their executive’s calendar.
Jan 22, 2026 - 11:22 EST
Investigating - Microsoft is investigating an issue where some users may be unable to access Microsoft 365 services, including Teams and Outlook. Microsoft is actively working to resolve the issue.

Observed symptoms may include, but are not limited to:
- Delegates accept calendar invitations on behalf of an executive, but the meeting does not appear in the executive’s calendar.
- Delegate views of executive calendars are not syncing or updating as expected.
- Calendar events created from shared mailboxes briefly appear after clicking Send, then disappear and do not appear in Sent Items (Outlook desktop and Outlook on the web).

AdminVPN - Service Degradation
Monitoring - Users outside Canada will experience connectivity issues at this time. Please use Admin2 instead, it will be a pulldown option in your Cisco client. Contact your local helpdesk if you require assistance.
Jan 23, 2026 - 08:00 EST
Identified - The issue has been identified and a fix is being implemented.
Sep 26, 2025 - 10:28 EDT
Investigating - We are currently investigating and issue with AdminVPN. Users outside of Canada may experience connectivity issues at this time. Users are advised to select the admin2 option in their Cisco client if possible.
Sep 26, 2025 - 10:11 EDT
The Teams meeting option is missing in OWA/new Outlook when scheduling from shared mailboxes
Identified - Microsoft Premier Support has confirmed that a silent license enforcement update affected shared mailboxes. They are actively working on restoring the Teams meeting toggle functionality for delegates. Unfortunately, no ETA is available right now. The M365 Admin Team is currently testing potential workarounds.
Jan 05, 2026 - 10:00 EST
Update - Microsoft Support is still investigating the issue.
Dec 08, 2025 - 12:44 EST
Investigating - Symptom:
In OWA and the new Outlook, the “Teams meeting” switch is missing when creating meetings on calendars tied to the shared mailbox accounts. No relevant changes were made on our side.

Current status:
We are working with Microsoft Premier Support and actively searching for workarounds.
Some users are reporting that the Outlook Classic Desktop app on Windows is not affected.
