Apple Prepares Mac Update to Fix Email Sync After Microsoft Exchange Change

Apple is preparing a software update for Mac computers to fix email and calendar sync issues caused by the recent Microsoft Exchange connection shutdown. Microsoft is turning off an older connection system for its Exchange email services this month, breaking the built-in Mail, Calendar, Contacts, Notes, and Reminders apps on Macs. The company is actively working on a patch to restore normal access. iPhone and iPad users are unaffected, as those devices use a different method called Exchange ActiveSync. The fix will arrive in a future macOS 27 update, shifting desktop apps to a newer standard. Until then, users can use the Outlook app or contact their technology department.
