Microsoft 365 outage affecting Outlook calendar sync and Microsoft Teams call recording

Microsoft is still reporting a service degradation across Microsoft 365 (incident IDs EX1550543 and MO1550821), affecting Outlook, Microsoft Teams and related services. Their mitigation is in progress and service has not been fully restored on their side.

On our side, call recording is now working for the majority of Outlook and Microsoft Teams calls. However, until Microsoft confirms the incident is resolved and shares its root cause, some calls may still fail to record.

Once Microsoft has resolved the incident, we will identify the calls that were not recorded during this period and share the list of affected meetings with impacted customers.

We are monitoring the situation and will post another update as soon as we have one.

Microsoft is reporting an ongoing service degradation across Microsoft 365 (Microsoft incident IDs EX1550543 and MO1550821). According to Microsoft, the Exchange Online/Outlook issue began at 8:17 AM PT on November 12, 2026, and the wider Microsoft 365 issue, which includes Microsoft Teams, began at 10:26 AM PT. Microsoft’s mitigation is in progress and service has not been fully restored on their side.

While this continues, Mindtickle users on Outlook and Microsoft Teams may see the following:

1. Outlook calendar sync is delayed or failing. Meetings created, changed or cancelled in Outlook during the outage may not be reflected in Mindtickle.
2. Some calls may not be recorded. This applies to Outlook meetings created or rescheduled during the outage, and to Microsoft Teams calls where the recording bot is unable to join.
3. The recording bot may join a meeting that was cancelled, or join at the original time of a meeting that was rescheduled.
4. Connecting or reconnecting an Outlook calendar may fail. Existing calendar connections remain authorized, so there is no need to disconnect and reconnect.
5. ILT sessions hosted on Microsoft Teams may show missing or delayed attendance data for sessions held during the outage.

Google Calendar, Zoom, Google Meet and Webex are not affected.

Once Microsoft has resolved the incident, we will identify the calls that were not recorded during this period and share the list of affected meetings with impacted customers.

We are monitoring the situation and will post another update as soon as we have one.
