Additionally to Judy, there's an addin for Outlook that can overwrite every
user's Master Category List with your categories at regular intervals. For a
free demo please see the link in my signature.

I am using Outlook 2003 in a XP environment, I have a shared calendar in a
Public folder that everyone in my department can see. My permission level
is
Owner. My question is: Can I edit the master list categories to have only
the catergories that I want others to use and delete all the default
categories? Will this affect their personal calendars?
