User set to "view only" on shared calendar keeps deleting events
Hello! I have a work calendar in iCal that I share with some others so they can see my upcoming schedule. I've restricted each person I invited to "view only" status in the drop down menu next to their email addresses, but one of those people keeps deleting every new event I add into my calendar. Not sure what I'm doing wrong, is there a way I can prevent this person from deleting my entries? Thanks!
