Hi Charlie , this is Kimberly. I'm glad to assist you today.
Some companies have policies that:
Block syncing to non-corporate devices
Require device compliance in Intune
Require MFA sign-in through a browser before sync starts
Test:
Go to https://portal.office.com/onedrive in your browser, log in with your work account, and try uploading a small file.
If it works there, the account is fine, but the desktop client is being blocked.
If you see a message about device registration or admin approval, that’s the cause.
Should you have more questions, please let me know.
Best regards,
Kimberly
