Using classic Outlook for Windows in business environments
Hi @ andy burky,
Can you currently log in to the M365 admin center using the global administrator?
You can try to disable MFA for your account by following these steps:
1. In the Microsoft 365 admin center, in the left nav choose Users > Active users.
2. Select the user you want to disable, choose Multi-factor authentication.
3. On the multi-factor authentication page, set its Multi-Factor auth status to Disabled.
Then try to log in to your Outlook to see if that works.
