Title: Some users may see a stale profile or unknown user for federated users in external chats and calls in Microsoft Teams

User impact: Users may see a stale profile or unknown user for federated users in external chats and calls in Microsoft Teams.

More info: Impacted users may see the issue occurring for federated users in chats, calls, channels, and any other service feature that shows federated users. Impact occurs in all Microsoft Teams clients.

Current status: Our fix has entered the early stages of its deployment, and while we anticipate that it’ll reach the affected environment by mid-April 2024, we’re closely monitoring its progress and will provide a more precise estimation once available.

Scope of impact: Some users interacting with federated users from any Microsoft Teams client may be impacted.

Start time: Wednesday, December 6, 2023, at 11:00 AM UTC

Root cause: An imbalance of service load on a portion of infrastructure responsible for populating federated users’ data and information in Microsoft Teams that’s resulting in impact.
