Integrate Apple devices with Microsoft Exchange (Apple Platform Deployment) (2026-04-14), read 2026-10-21.

What to do. Apple says a future update to macOS 27 moves Mail, Calendar, Contacts, Notes and Reminders to Graph. Until then, Mac users with Exchange accounts in these apps rely on EWS: find Apple's app in your EWS usage report and keep it on EwsAllowedAppIDs.
