Issue Status: RESOLVED

Issue Description: Users may be unable to play migrated Stream videos in Microsoft Stream.

More info: Users attempting to play impacted Stream videos will encounter the error message: “This browser or app can’t play the video. Something might be outdated or not supported. Try again using a different browser or app.”

Final Update: 17/04/2024 08:33:00 AM – The repair process has completed, and Microsoft have confirmed that the overwhelming majority of customers are no longer impacted and that the previously affected files are available and functioning as expected. However, they have identified a limited subset of customers with lingering impact from this issue and they are publishing a separate communication to track the remediation effort going forward for those organizations.

Scope of impact: Any user may be unable to play migrated Stream videos in Microsoft Stream.

Root cause: A recent feature update, intended to enhance the reliability and stability of our service, contained a code regression that impacted Stream video files that were migrated between Saturday, February 10, 2024, at 2:00 AM UTC, and Tuesday, February 20, 2024, at 9:30 AM UTC, causing them to be unable to play.

Next steps: Microsoft are reviewing their feature update procedures to ensure issues of this nature do not occur again.
– Microsoft are preparing additional communication for the limited subset of customers who are still affected by this issue.
