We have moved a user's calendar from their C drive to the Exchange Server.  
We copied the contents on the old calendar to the new and that worked fine.  
The problem is that the Exchange Server calendar does not appear to be the
primary calendar so when other users try to view the person's calendar, they
get the old one and the user gets the old calendar by default unless she
makes a special effort to select the Exchange Server one.  We are not able to
delete the old calendar.  I've searched this newsgroup topic and read what I
think is the answer to this same question twice - but they were short cryptic
answers and I didn't understand either one - I feel stupid!  Could anyone
explain it in a way that even a person like me could understand?  Thanks
