Hi @Renaldo-2294,

Does anyone else have the same issue in your organization?

Have you tried to change another device to access Teams?

In this case, we recommend you try to perform a clean boot in Windows to block the third party application that affect Microsoft Teams login normally. For more details about how to perform a clean boot, you can learn it from:

In addition, please check if you have opened UDP port 3478-3481 in your firewall.

Hi Jimmy !
We did a clean boot and also had to uninstall the Anti virus that was blocking the application and then thereafter re install.

Thanks for the assistance
