I have no issues in Outlook 365 with being a global rebuild Outlook data file quickly admin and having modern authentication with multi-factor authentication. If you have an issue that's not listed in this article, go to the following Microsoft TechNet wiki page. The wiki page lists other known issues and workarounds. Since Microsoft recently demanded OAuth2 authentication, I've been trying everything I found here and at Microsoft, but every 'help' webpage to setup Hotmail and Thunderbird seem badly outdated. If the error you are encountering is not listed, please create a ticket on our Email and Calendar Help page for assistance.

Some users on macOS 10.14 have experienced issues logging back into Mac Mail after Modern Auth is applied to their accounts. Specifically, after successfully responding to the Duo prompt, the pop-up window will remain blank except for a spinning icon and never finish adding the account to the application. This issue has been resolved by having users connect to the UO VPN when initially setting up their account with Mac Mail. After logging in successfully once while connected to the VPN, any removing or re-adding of the account again to Mac Mail should not need the VPN. In many cases, simply removing the account from the application and re-adding the account using the standard Sign In method will resolve any issues being experienced when Modern Authentication is first turned on for an account. Please note that this can take a significant amount of time, depending on the size of your account and your other connected applications (Contacts, Calendar, etc).
