I have a Direct Booked resource mailbox that does not remove cancelled
appointments from its calendar.  This resource un-attended and I would like
to find a way to removed them automatically.

I tried using the Auto Accept agent instead of Direct Booking. This dose
remove cancelled appointments, but does not provide instant feedback of a
busy period before sending the invitation.  The Direct Booking method will
prevent a invitation from being sent to all others until the resource is
free.  This user experience cannot be changed at my company...so, I need to
continue with Direct Booking.

Is there a automatic or scripted way to removed Cancelled events on a
resource calendar?
