Title: Some users may have been unable to start recordings or transcriptions in Microsoft Teams

User impact: Users may have been unable to start recordings or transcriptions in Microsoft Teams.

Final status: We've determined that an unexpected spike in user requests caused a section of infrastructure that facilitates recordings and transcriptions in Microsoft Teams to perform below acceptable performance thresholds. We've optimized traffic and performance parameters on the affected infrastructure to remediate impact and after a period of monitoring service health, we’ve confirmed that the issue has been resolved.

Scope of impact: Some users located in Asia-Pacific that were attempting to start recordings or transcriptions in Microsoft Teams may have been impacted.

Start time: Monday, May 11, 2026, at 5:00 AM UTC

End time: Wednesday, May 13, 2026, at 9:26 AM UTC

Root cause: An unexpected spike in user requests caused a section of infrastructure that facilitates recordings and transcriptions in Microsoft Teams to perform below acceptable performance thresholds.

Next steps:

- We'll continue to closely monitor the affected environment to ensure the service remains healthy, and we'll review our service resilience processes to help us reduce or avoid similar issues in the future.

This is the final update for the event.
