Hello, We are having a problem where a few of our executives are recieving meeting request on their personal calendars from other users. right now it seems like anyone can do this on anyones calendar. it will show up on the calendar as tentative but there are so many that it is hard to go and weed out the request when he is actually making an appointment on his calendar. How do i block users from doing this and only delegate His Secretary to modify calendar. Also i was looking at calendar properties, under administrtion tab, all that is greyed out except initial view on folder.
