Microsoft Enterprise Exchange Problems on iOS 16

Since the update to iOS16 and the change to modern authentication, I cannot get my business Exchange account to work properly on the native iOS Mail app for any iPhone or iPad device.

This problem has persisted since iOS16.0 through 16.0.3 and even the forthcoming iOS 16.1 RC. Push mail, or Fetch mail, no longer works. And when in the Mail app for the iOS device, it either gets stuck on "Checking for Mail" or it eventually fails with an error saying “Cannot Get Mail: The connection to the server failed”. It randomly will start fetching mail again, though not through Push or Fetch, only to get stuck at random intervals with "Cannot Get Mail: The connection to the server failed."

I've tried deleting and re-adding the account, resetting all settings on the devices, and even reinstalling iOS 16 fresh and re-adding the accounts. All to no avail. We've checked the Azure AD for error messages during these failures, and we cannot find any errors.

Absent an iOS 16 bug that may or may not be addressed, is there anything I am missing to fix this? I do not want to use the Outlook app, because I manage multiple accounts through the Mail app and do not want to be using multiple apps just to manage mail.

    I am having the issue. I don’t get mail until I go into the mail app then it updates with several email.

    Thanks for the advice. I think that is indeed going to be the last resort and to just wait and see.

    I’ve tested this on iOS 15.5, 15.6, 15.7, 16.0, 16.1, and 16.2 beta today and the only versions that work just fine is iOS 15.6 and 15.7.

    Apple and Microsoft started switching to Modern auth and updated iOS 15.6 to support it: https://techcommunity.microsoft.com/t5/exchange-team-blog/microsoft-and-apple-working-together-to-improve-exchange-online/ba-p/3513846 

    I guess that didn’t carry past 15.7 so we’re stuck for now.

    I'd say using Outlook app for iOS is a temporary workaround. It will (hopefully) be fixed by either behemoth company.

    Hello again, Simbarashe:

    This continues to be a problem with the latest update to iOS16.1 for me on any Apple device running 16+.

    I called Apple Support again and spent an hour on the phone troubleshooting. They eventually told me, once again, it is not their issue but a Microsoft one.

    Given the advice to use the Outlook app instead and the back and forth finger pointing between vendors, should customers assume that Apple and Microsoft are no longer supporting Exchange on Apple's native Mail app?

    Regards,

    Hello Simbarashe,

    Your summary of the issue is correct. Outlook Web, Office 365, and the Outlook app work fine. It is indeed only broken on iOS's Mail app.

    I tried to contact Apple Support, but they instructed me to contact the provider since it isn't an iCloud Mail issue.

    I am not sure I have a good path to get this fixed.
