Issue Status : RESOLVED
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.
Final Update : 04/10/2022 08:56:00 AM – Microsoft’s fix to address the affected Windows users is complete, and they have tested to confirm that the issue is no longer occurring and impact is remediated.
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 steps : Microsoft are reviewing their Microsoft Teams desktop client update procedures pertaining to meeting join functionality to prevent similar impact in the future.
