I have a 2016 exchange with autodiscover.
Mail receives and sends works as a charm, auto discovery also works, except on iOS clients.
If I add the mailbox on Outlook 2019 or 2016, the settings are found through Autodiscover.
I can add the same mailbox on Apple Mail and Autodiscover works as well. I just need to fill in the username / e-mail address and password.
But as soon as I want to add this mailbox to an iOS device (12.4.1), whether it's an iPhone or an iPad, it can not find the settings automatically.
Is there a difference between Autodiscover for macOS and iOS?
