“Sharing from this account has been temporarily blocked.  To get unblocked, please verify your account info.”

I have tried the following to verify my account to no avail:

1. Removing and adding a phone number

2. Changing the login password

3. Removing an alias email

4. Adding additional information to the profile

5. Confirming my email address and phone number by entering codes I receive in messages directly from Microsoft.

I have read online and it seems as though this is a Microsoft issue and not something I can correct on my end. Is there anything I can do to re-confirm my account and begin sharing folders with other users once again?
