Accept/Maybe/Decline Missing in Apple Mail I'm using Apple mail with a fresh install of MacOS and I'm missing the Accept/Maybe/Decline buttons on calendar invites. My company uses a Exchange 2013 server and some other users do see the buttons. For me, I just see an email with an attached .ics file for the same invites.

Expected behavior seen by some people....


How my mail app shows it...
Open the Contacts app, select your own email address in the list of contacts. In the menu on top of the screen, go to "Card" -> "Make this my card". Reload calendar. Then it should work, you will get a notification popup with accept/decline buttons. (I just had the same problem, on a Mac running Yosemite)
