Microsoft Reference : TM256447

Issue Status: OPEN

Issue Description: Users leveraging Microsoft Teams Meeting Room devices can’t join meetings, make calls, or sign in to Microsoft Teams. More info: Microsoft Teams Meeting Room devices leveraging OS version 18363.1556 may be affected. We recommend restarting affected devices to mitigate the problem. Our testing suggests thus far suggests that only a single restart is needed. More information about the affecting OS build can be found here: May 11, 2021—KB5003169 (OS Build 18363.1556) (microsoft.com)

Scope of impact: Your organization is affected by this event, and any Microsoft Teams Meeting Room device updated to version 18363.1556 may be affected.

Current Update – 17/05/2021 09:45:00 AM: Microsoft have determined that a recent OS update (18363.1556) is inadvertently preventing some Microsoft Teams Meeting Room devices from accessing the Microsoft Teams service, and resulting in various impact scenarios. Based off our analysis, we suspect that rebooting the affected devices manually, through PowerShell, or the Microsoft Teams Admin center, mitigates the problem. Microsoft are reviewing available logs and testing internally to determine if additional remediation steps are required.
