Microsoft Plans Automatic Upgrade of Apple Mail App Profiles

Tens of millions of Apple devices connect to Exchange Online user mailboxes. The mail app profile on many devices still use basic authentication, and that's a big problem because Microsoft will start to remove support for basic authentication for EWS and EAS, the two connectivity protocols used by Apple devices, from October 1, 2022.

Microsoft Announces the Future for Exchange Server

On June 2, Microsoft made a bunch of announcements covering the future for Exchange Server.
