Yosemite 10.10.2 Situation: - Calendar.app - Shared calendars from my co-workers - Calendar server: MS Exchange on the local network. Problem: Invitations directed to my co-workers shows up as notifications to me (in the upper right corner of my screen), and it's extremely annoying! Especially when I'm too fast and click "confirm"... In Calendar Preferences > Alerts I have set it the only logical way (look at the attachment). I still want my own notifications to show, therefore I don't want to check "Turn off invitation..." Any ideas?
