macOS 26 and iOS 26 issue with Exchange calendar
- Every time I receive a calendar invite on Exchange, both my macOS and iOS devices require that I respond to the invitation. If I respond on one device, the other will still display a notification to RSVP to the event.
- Additionally, for declined events, the macOS calendar adds "Declined: " to the beginning of the meeting name, displaying it alongside the other events. "Show Declined Events" is checked on both macOS and iOS; however, unchecking it on macOS Tahoe's calendar does not hide the declined events, as they appear like regular events but with an updated title. On iOS 26, however, the declined events are not shown even when "Show Declined Events" is checked.
- When I remove and re-add the account on the macOS calendar, I have to re-decline the last 15 to 20 events that I previously declined.
