MFA is triggered every time an O365 application is started
Hello Community, I'm working together with a client on moving their on-premise mailboxes to Exchange Online. As a separate process, we're activating Azure MFA for migrated users that are already ...
After doing the MFA exchange does e-mail work properly just until they restart they get prompted again?
Going to assume they are on the same outlook client that supports Modern Auth etc?

Exactly. Everything works as usual after authenticating, the users have access to their mails. But after closing / shutting down the Outlook application and opening it again, they're prompted again to do MFA.
The subscription product is Microsoft Office 365 ProPlus, the Outlook version is 1808 and 1810.
Get them to try on a different machine, and similarly get a different user to try on their machine. That way you will know for certain if its something with the user profile. You can also do the same with respect to network location (and maybe check if they are subject to any Conditional Access policies forcing MFA).
