Humm, here in Outlook 2003, it lets me delete it without so much as a
whimper. Perhaps you are archiving to it or it's open or something.

To save space on the server I have set a rule to automatically move
everything I receive to a different folder that is in a local pst file. An
unfortunate byproduct of this is the new pst also has a calender. I randomly
get meetings added to this new calendar. Some meetings go to my server based
calendar, some go to the pst based calendar. Outlook tells me I can not
delete the calender in the pst. What can I do to get rid of this extra
calender or at least disable it from being used?
