I've read here that categories follow the users outlook data file unless  
it's assigned to a public folder contact, in which case everyone can see it
when they view the contact.  With that in mind, I have 2 categories that
follow everyone everywhere.  I'm not sure where they are setup, is it in
exchange? Or active directory?

Whenever anyone views contact categories, whether it's their local contacts,
or public folder contacts, everyone see's the PXE CONTACTS category, and the
APS CONTACTS category.  This makes sense because we have two organizations
using those initials.  But where are these setup??

Thanks!
