All of my users are synced to my Duo portal from Azure AD and all of them have enrolled their mobile devices. I’ve setup an authentication proxy and have my default domain ready to go in my tenant. My next steps are to federate my domain then add the Office 365 application in the Duo admin panel. Will my users lose the ability to login after I federate my domain? I assume they won’t start using Duo for authentication until I get the application setup in the Duo admin panel?
The majority of my users have Outlook installed and we see the Office 365 prompt to login. When we do cutover to Duo for authentication will we start to see a Duo prompt rather than a 365 prompt?
