Hello clarkmartin1968,
Thanks for posting in Microsoft community.
Based on your scenario, if you are using Office 365 for Business account, we recommend you contact your Office 365 administrator disable MFA for your account, and your admin can help you enable again.
To disable and re-enable multi-factor authentication, please refer to following article:
