I've been tasked with cleaning up our companies contact database sitting on our Exchange Server 2003. The rub is this database of contacts has been neglected for the past couple of years and is now a bit messy.

My issue is I have say a person named 'Bob Smith', and Bob is listed in multiple categories, 'Students' and 'Student'.

I would really like to remove the 'Student' category from Bob and anyone else out there that has the same category.

My question is, is there an easy way to edit the master category lists for contacts on the exchange server?

I feel like I am missing something simple here since if I were playing with the categories that I use, to say organize email its very easy to do so, but I can't seem to find the proper way to do it for categories that are up on the server.

I'm attempting to work through Outlook 2007 and Exchange 2003.

Any insight would be very helpful as I really don't want to change 8000+ contacts by hand.
