How to delete a calendar or rename it

I have Outlook 2003. My husband set it up several years ago before I joined
him in the business. I want to delete the calendar with his name or change
it to my name. I get the message "unable to delete this folder. Righ-clice
the foler and then click Properies to check permissions for the folder. See
the folder owner or your admin to change permissions. "Husband" is a special
folder. Special folders cannot be deleted.
I believe the original set up may be part of the problems I have with
syncing with outlook on my home computer. Any help or thoughts will be
appreciated.
