From: H+E on
I have shared my calender with a few people. The sharing permission is that
of Author, so all whom the calender is shared with can enter and delete their
own appointments to the shared calender, but can only view other people's
entries. Everyone seems to be able to do this bar one person. Every time he
tries to enter in an appointment it tells him that he is "unable to open the
free/busy information".
Do you know why this would be occuring?
