Final Update: 07/03/2025 08:52:00 AM – Microsoft have completed the deployment of their code fix and confirmed in their service health telemetry that impact was successfully resolved.

Scope of impact: Your organization is affected by this event, and some users may be unable to screenshare after newly installing Microsoft Teams for macOS version 15.X.

Root Cause: A recent code change for Microsoft Teams has introduced a code error for devices on macOS versions 15 and above that prevents a popup to enable screensharing from being presented to affected users.

Next steps: Microsoft are reviewing their code change testing and validation procedures to identify how impact was missed to better prevent similar future occurrences.
