iOS 15.6 will migrate iPhones on basic authentication to modern authentication

[BetterLicenses]

Microsoft is probably foreseeing a lot of support requests so they joined Apple and provided tenant admins a way for iPhones running iOS 15.6 to automatically exchange user credentials for OAuth token, migrating devices from Basic Authentication to Modern Authentication.

We've made a to the point post on how to do it along with other protocols (IMAP, SMTP) and Microsoft has released a detail post also.

This should make things easier not forcing users to re-configure their iPhones Mail Apps accounts to get modern authentication.

If devices are Intune Managed with OAuth enabled in the Email profile does the device transition to modern authentication if is NOT on iOS 15.6. If a device is not on iOS 15.6 when Microsoft deprecates legacy authentication, and the profile has OAuth enabled will the email profile break?
