Apple Mail Client - And Emplorer access

I know an employer can brick a device if you use the Exchange Outlook client. Can that also be done through the Apple Mail Client?

Yes, if you use the Apple Mail client to host the Exchange account. Connecting an Exchange account to your iPhone gives the administrator of the Exchange server rights to manage most of the security features of your phone; it also legally gives the administrator ownership of all data on the phone. That’s why many people carry separate personal and business phones.

Using iOS Mail in Azure AD Hybrid Environment ActiveSync Disabled? Hello! IT Admin, here. Our company is using Azure AD - Hybrid. We use Modern Authentication - MFA for our users to sign in, and we've disabled ActiveSync, per Microsoft's security recommendations. We have a few Apple users in our environment that would much prefer to stick with iOS Mail & Calendar, rather than use the Microsoft Outlook app. Since we aim to please, we have been attempting to connect our O365 accounts via iOS Mail, with no luck. The sign-in process is "Exchange" -> "Sign in using Microsoft" -> MFA prompt -> Apple Internet Accounts prompt -> "Exchange Account - Unable to verify information". In Azure AD -> Enterprise Applications -> Apple Internet Accounts, everything looks peachy. If we look at an AD user's Login logs that has attempted to connect their email to their iPhone, we see three instances of Apple Internet Accounts; an "Interrupted", a "Failure", then a "Success", all within four seconds. The descriptions are: Status: Interrupted Sign-in error code: 50058 Failure reason: Session information is not sufficient for single-sign-on. Status: Failure Sign-in error code: 50199 Failure reason: For security reasons, user confirmation is required for this request. Please repeat the request allowing user interaction. Status: Success We get the exact same behavior on iOS 13.7, iOS 14, and iOS 14.0.1. We tested one account with ActiveSync enabled, and that account connected without any problems. Is it even possible? Can iOS Mail connect to an Exchange account without ActiveSync? Thank you! --Ryan C.
