Office 365 MFA Enabled Users and the Apple Mail app for iOS Concern
JPSAndyJ I'm the IT manager for our company. We have BYOD device policy for most of the iPhone users and only certain employees on InTune. We have had numerous issues which are still ongoing. Due to repeated breakin attempts I had to enact a stricter authentication policy which blocked basic authentication. Users began reporting issues, and even before one user who had limited admin rights had issues with his device and MFA. I have a work around for the recent issues where the iPhone asks for a password using basic auth. Open another iPhone application which forces the use of modern authentication, either Teams or Outlook for iOS. This will then authenticate and the password prompt from the native mail app will go away. For the MFA user I had to remove their profile and add it back. Then use this same method to force modern authentication. Try that.
Jim_Hill that's a very good point and I'm glad you brought it up.
Modern Auth with O365 works around the premise of "authentication tokens" and I believe once a user's phone has said token, they can authenticate with virtually any aspect of the O365 platform.
So yes, authenticating with any app that requires Modern Authentication should authenticate with every O365 service on that device.
Thanks JPSAndyJ I would just have recommended the use of the Outlook for iOS app but the current app does not provide ready integration with iOS contacts, making it hard for users who want a global contact set on their phones.
Jim_Hill Same with us. We used that as a "quick fix" until we figured out the whole MFA situation on iOS, but users weren't happy with the fact that it didn't sync their phone contacts & calendars.
It is a great workaround though in the event that all else fails.
