For some reason, for exchange accounts, if I accept/deny calendar invitations on one computer, it would still stay as an alert on my other computers. The alert would not ask me to accept/reject, instead it would just ask me to dismiss it with an "ok" button. It's super annoying because that means I have to click "ok" for each calendar invite for each computer I have.

Is there a way to fix this or at least a quick way to dismiss all incoming event that have already been accepted?

Hold down the alt key when you have the invitations list in view.

All the OK buttons will change to Ok All and all the Accept buttons will change to Accept All

Clicking the Ok All will clear the invitations with just the OK All.

The other buttons do not change annoyingly. As I would like Decline All

    alt is useful for activating 'alternative' menu items along the whole system. Commented Apr 21, 2015 at 5:16
  • @CousinCocaine , Correct. That why it was the first thing I tried. :-)

    There are no OK buttons. There are only Maybe, Accept, and Decline buttons, and only Accept becomes "Accept all" Commented Oct 14, 2017 at 12:12

    A lot of my notifications are for events that I've already accepted elsewhere, and are now in the past. Does this send a notification to the inviter?

Instantly clear notifications in calendar inbox, never get those again:

Calendar > calendars Next to each calendar (shared/subscribed) is an “info” button. Click.

Shared Changes: turn off. This will instantly clear the inbox.

FYI: Below the color choices is Event Alerts: choose on/off to get notification for the upcoming events (day before, hour before, time to leave, etc), whatever alert option was initially used when event was created.

  • This solution is for iOS. I believe the question refers to Calendar mac app. Commented Sep 13, 2020 at 3:36
  • On MacOS Calendar Version 14.0 (2964.2.2), I do have in information entry in the context menu, but that only seems to allow toggling event alerts. I would love to see a "shared changes" option as well.
