2] Verify On-Premise UPN Suffix Domain
Next, check if the on-premises UPN suffix is a verified domain. If not, wait for the next time until the directory synchronization runs or force directory synchronization. Doing so can help if the user’s UPN has changed, but the directory hasn’t synchronized.

Check if Microsoft servers are under maintenance. To do so, open the Microsoft server website or follow @MSFT365Status on Twitter.
Also, check your Microsoft Account and make sure it is still active. If your account gets deactivated somehow, Microsoft offers a 60-day grace period to recover it. Once this time passes, your account will be deleted permanently.
4] Contact your Admin
Lastly, contact your admin and see if they can help fix the error. The error may lie on their end; if that’s the case, you can do nothing but wait.
