Microsoft Reference : TM424840

Issue Status : ONGOING

Issue Description : Users are intermittently dropped from meetings when using the Microsoft Teams desktop client.

More info : This issue is primarily affecting MacOS users; however, a small percentage of Windows users may also see this problem.

Users who can join the meetings through the Microsoft Teams web or mobile apps can do so to avoid impact.

Scope of impact : A subset of MacOS users and potentially some Windows users are intermittently dropped from Microsoft Teams meetings when using the desktop client.

Current Update : 27/09/2022 14:05:00 PM – Microsoft confirmed that the deployment of the fix for the affected Windows users has begun and currently stands at 20 percent saturation. They also anticipate its completion by the next scheduled update.

Root cause : A recent update to improve client rendering and telemetry handling introduced a Join button meeting code issue, resulting in conflicting commands and ultimately dropping users from meetings.

Next update by : Wednesday, September 28, 2022, 6:00 PM
