Title: Users see blurry videos on Microsoft Teams live events playing pre-recorded videos
User impact: Users saw blurry videos on Microsoft Teams live events playing pre-recorded videos.
More info: The issue only occurred when joining Microsoft-hosted Microsoft Teams live events from the “Calendar Peek” view in the Microsoft Teams desktop client. Users attending such events were recommended to join through a direct link via their web browser or through their Outlook calendar instead of using the Microsoft Teams desktop calendar.
Final status: Deployment of the fix is complete, and we’ve monitored service health telemetry to confirm that impact is remediated.
Scope of impact: This issue may have impacted any user attempting to watch Microsoft-hosted Microsoft Teams live events playing pre-recorded videos.
