How to setup Duo Authenticator App

Android users accessing their work email must use the Microsoft Outlook for Android app. The native email app doesn’t support the correct method of authentication needed for DUO MFA.

Apple users can use either the Outlook for IOS app or the default Mail app, but Sentrian recommends Outlook for IOS for the best experience with Office 365.
