Office 365 MFA Enabled Users and the Apple Mail app for iOS Concern

Office 365 MFA and the Apple Mail app for iOS concern? We ourselves and several customers using Office 365 have noticed a recent issue with the Apple Mail app for iOS when Office 365 MFA is enabled. ...

I suggest testing iOS 12 (beta 6 is out now). I presume Apple has done more engineering on MFA (OAuth), plus OAuth can now be configured via a MDM profile in iOS 12 (for those who need to manage and mass-deploy Exchange/ActiveSync settings to hundreds - or thousands - of iOS devices). Currently Mail.app's OAuth/MFA settings must be configured manually in iOS 11.

 

iOS 12 will likely be released in September 2018.

    " MFA (OAuth), plus OAuth can now be configured via a MDM profile in iOS 12 "

     How?

     

    We've got O365 MFA working fine. We are turning on basic MDM for a group of users.

    Problem is that the activesync account created by the policy on iOS devices requires an App password for the native mail app.

      Jason Simotas I believe I am having exactly the same problem. It sounds like full Intune administrators can enable OAuth in their profile, but I can't find a way to do this with Office 365 MDM. Have you found any way to deploy a mail profile using Office 365 MDM that works with MFA/Modern Auth?

        snorma01 I have run into this issue as well. Most all iPhone users have the MFA loop and i cannot seem to figure out hot to stop it. Because some users refuse to use the Outlook app
