Is there any way to "lock" an appointment on a calendar?  Several users have
access to our bosses calendars and the ability to book meetings for any of
these people.  Is there any way to lock an appointment so someone can see it,
but not take if off the calendar?  I don't mind if they want to book 10
meetings at the same time but I have certain meetings that I need to stay on
the calendar.  Thanks for your help.
