Hi @JimmyYang-MSFT ,

I confirm issue is reproduce in my environment after reinstalled Teams client.

The error message is appears after sign on => " Sorry we encountered a problem please restart "

I also confirm, there is no issue when I log in with Teams web client.

I have updated my Teams client but without result.

I have the impression that the Teams client does not recognize my business account

Thansk fo your help

@Jean-Marc Ferrandis

Thanks for your feedback！

If there is no issue before this issue happened, this issue may related to time zone. In this case, we recommend you go to control panel -> Time & Language-> Set time zone automatically OFF and select manually the time zone and then synchronized your clock. Then restart your computer to see if it can be fixed.

In addition, perform a clean boot to exclude whether a background program is interfering with Teams.

Moreover, check the health status of Microsoft Teams in Office 365 admin center > Health > Service health.
