Issue Status: RESOLVED

Issue Description: Users may see stale profile pictures or profile information for other users within Microsoft Teams.

More info: This issue strictly affects some users attempting to view the profile picture or information of other users who modified either field after Tuesday, January 27, 2026, at 9:00 AM UTC.

Final Update: 03/02/2026 08:56:00 AM – Following our reversion of the offending infrastructure update and the isolated code regression, our internal service telemetry has verified that impact has been remediated.

Scope of impact: Some users viewing the profile pictures or profile information for other users within Microsoft Teams may be impacted.

Root cause: A code regression contained in a recent update to a portion of the Microsoft Teams service infrastructure is causing impact.

Next steps: Microsoft are further analysing the offending infrastructure update and the introduced code regression to help us improve our pre-deployment testing and validation processes in our effort to prevent similar issues in the future.
