User impact: Users may have been unable to turn on captions for Town hall events in the classic Microsoft Teams desktop client.
More info: Specifically, when users clicked the Captions button to turn on live captions, nothing happened.
Users could have switched to the new Microsoft Teams desktop client to avoid this issue.
Final status: We have successfully deployed the fix to the affected infrastructure and after a period of monitoring, we’ve confirmed impact has been remediated.
Scope of impact: Users on the classic Microsoft Teams desktop client who were attempting to turn on captions for Town hall events may have been impacted.
Start time: Thursday, November 30, 2023, at 4:15 PM UTC
End time: Thursday, February 8, 2024, at 8:36 PM UTC
Root cause: A change to the Microsoft Teams service introduced a regression which resulted in different caches being read from and written to for captions, resulting in impact.
Next steps:
– We are reviewing the affected infrastructure to determine what improvements can be made to prevent similar issues from occurring.
This is the final update for the event.
