Microsoft Teams user status unknown
The issue is concerning every Office 365 account we have signed into Teams with this particular device. Using my own laptop for example the issue doesn't exist.
As I mentioned before this had worked in the past. The problem started last friday and was "fixed" for a moment after a reset for the device.
AleksiBe Got it. So, something with the device is happening which let Microsoft Teams not working correctly anymore.
If the device is working as expected after a full device reset, you should investigate what happens afterwards. Are there any software packages deployed to the system via a software management tool. Any antivirus tool, firewall software, VPN software or driver updates? Please check which software is installed in the period where the Teams client works till it isn't working anymore.
