I am able to log in fine on the web , but the phone keeps repeating the same error.

This is happening on Multiple phones and multiple accounts.

Any ideas, did MS change anything recently?

I have the same issue with 2 T42S phones. I created a ticket for support team, no news yet. In Active Directory I found following error:
Error code: 50199
Error reason:
For security reasons, user confirmation is required for this request. Please repeat the request allowing user interaction.

Looks like it might be something @ Microsoft end that changed and blocks the Authorization.
