Any one know how to block meeting requests from getting inserted into a calendar? I just want the option of previewing the message/meeting request before it hits the calendar for accept, deny or tentative. I've a user who believes that since this request is showing up in her calendar that the time has been blocked out. I've told her several times this is not the case but she insists she doesn't want to see anything in there that she doesn't put in there herself. I had a hard time holding back on the "then try a paper calendar".
