I would suggest that you try to use the tool here in setting up your account:

Might be helpful if you take a screenshot of the error message and post it here. Another thing is if your email address domain is used as a website as well, verify if the certificate of the website is still valid.
A long time ago my Microsoft Account was a Google email address: mailto:xx@gmail.com . Then I created mailto:xx@outlook.com account with the previous address as backup. I recently removed Gmail address as secondary. However now Outlook Microsoft 365, when I added mailto:xx@gmail.com as Gmail account, adding mailto:xx@outlook.com does nothing - no error - it seems outlook account is still recognized as gmail one through my old PST files stored in the disk. Windows 10 Outlook have no such problem- Gmail and Outlook accounts are separate.
What shall I do get Outlook.com account in Outlook Microsoft 365?
