Hi @Calin Crisan
According to your description, the situation on your end is likely caused by your organization's settings/policies (e.g. conditional access policy).
You can try the following steps, and then check if it still happens or not.
- Please sign out your accounts from Office applications, then close all Office applications.
- Open File Explorer, paste the following path, and delete all files and folders.
%localappdata%\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy
- In the Windows search bar, search for "Access Work or School".
- Check if you can see your business account in "Access Work or School".
If you don't see it, please select Connect and add your business account.
If you can see it, please select it and select Disconnect. After that, please click "Connect" and log into your account again to register the device.
- Run one Office application, such as Word, sign into your account, and check again.
