Issue Status: RESOLVED

Issue Description: Users may see incorrect presence information in Microsoft Teams.

Scope of impact: Impact was specific to some users who were served through the affected infrastructure in Europe, Middle East, and Africa.

Root cause: A section of caching infrastructure, responsible for reflecting correct Microsoft Teams presence information, is performing below acceptable performance thresholds.

Next steps: Microsoft are reviewing performance data and trends on the affected caching infrastructure to understand why the performance issue occurred, in order to help prevent similar impact from happening again.
