I have editor delegate priveleges for someone's calendar and want to keep
canceled meetings on their calendar. When I receive a cancellation on their
calendar and delete the message, the appointment falls off the calendar the
majority of the time. I am not selecting the "remove from calendar" option
in the cancellation notice. It seems that some stay on the calendar when I
delete and some fall off. It seems like I have to keep it in my inbox until
the date passes, which is not effective.
