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.

    If you are using an Exchange account in the Mail app, try to disable Notes sync for it (settings > mail > accounts > exchange > turn off notes sync). It worked for some devices for us.

    This actually worked! It took a few tries but eventually turning off Notes synching got Push mail working again and stopped the error connecting to server failures. Must be a bug in the iOS Notes synching that’s gumming things up, but this is a good work around for now.

    Much appreciated!

    I’ve hit a brick wall with outlook running imap accounts on iOS

    16.1. My outlook accounts keep failing to populate and gmail accounts have to be signed into repeatedly. Tech support are struggling as they only seem able to respond by email.

    I was looking at this article regarding Microsoft getting rid of Basic authentication processes for tenants around October at random dates, issues started last friday, you would need to reenable basic authentication and or set up a modern authentication on both the microsoft admin center and on the Iphone, some people in my work office are running 15.6-16.0+, One of my co-workers has 16.0 and his exchange is working fine since we have set up Modern authentication processes on both the admin exchange center & And through our certificate provider that pushes phone updates/ apps through our iphones.

    Heres the article regarding the removal of basic authentication processes starting in October on random dates, hope this helps https://techcommunity.microsoft.com/t5/exchange-team-blog/basic-authentication-deprecation-in-exchange-online-september/ba-p/3609437

    This is also the exact same problem I am having, the 'automatic reply' is stuck on loading, which shows that its not connected to the exchange server, the contacts and calendar sync ok, but notes has a real problem, the same 25 notes load and then do not interact with the server at all.

    After hours on the phone with Apple support, sending them multiple videos and screenshots of the issues, I have now heard nothing back from any of them and can't get hold of anyone to help me!

    And if you do get iOS 16.1 to authenticate—-good luck syncing with Exchange.

    Experienced either lost connection to server or incomplete sync with Notes on Exchange.

    A glorious headache.…please fix soon.
