I assumed that a "new mail profile" is a new email account, so I deleted my
old email account and added it back in again.  No luck on the calendar.  

I then searched and found an article here called:  "Use the Inbox Repair
tool".  I ran it and got some lost and found and recovered folders which had
the calendar appointments.  But I still have no calendar icon.  I created a
new Personal Folders' folder and imported the old outlook.pst items in.  I
have a Calendar Icon now, but an empty calendar now.  And the recovered
folder now has lost the calendar appointments it had listed in it.  

Question:  Does the Outlook.pst file lose calendar items when it is renamed?
I renamed it twice now and both times it lost the calendar items!  How do i
get the appoitments back, and into my calendar too?
