iOS mail app needs consent since iOS 11
We noticed that auto-configuring the iOS mail app needs user consent in recent iOS versions.
The instructions are also updated by MS https://support.office.com/en-us/article/Set-up-email-us...
There is no issue here, the folks at Apple simply updated the app to use Modern authentication, finally. It's actually a good thing as it means you can have "native" MFA experience and so on. The consent is also part of this, and you already know how to control it, which is another good thing - you have a better understanding which users are using which apps, etc. You are certainly not the first organization to disable that option :)
