We are about to engage DUO for 2FA and a question came to mind.
Like any org we will assign DUO to protect out O365 environment. We have desktops as well as mobile devices that sync email from Exchange online in O365. I understand that when an employee logs into O365 DUO will challenge them for acknowledgement and allow access.
How does this impact say a mobile phone where it is constatntly polling the Exchange online server for email updates?
Why the question. If DUO will challenge the user to “authenticate themsleves” every time a mobile device interacts (either recieves an incomming email or sends one) with a mobile device it would be impractical
