Scope of impact

Some users expecting to receive meeting start notifications in Microsoft Teams on Android devices may have been impacted.

Root cause

A recent notification service change intended to address an unrelated issue affected meeting-started notifications for Android users.

Next steps:
- We're reviewing the recent notification service change to understand why impact to meeting-started notifications wasn't identified during our pre-deployment testing processes, so that we can prevent similar issues from occurring in the future.

This is the final update for the event.

To see whether your own tenant is affected, check Service health in the Microsoft 365 admin center. Only a backup outside Microsoft protects against data loss, and only a tested break-glass account against locked-out admins. We set up both in fixed-scope sprints.

This is the view of a Swiss Microsoft 365 tenant: services not licensed there are missing, and individual issues may affect your tenant differently. Microsoft names the region only in the issue text. The Switzerland view shows issues for Switzerland, for Europe in general and those without a region, but not issues that only name other countries such as Germany or the UK.
