How do I change the default filter behind the Outlook Addressbook

[Bob Manthey]

This is the default LDAP Query filter behind the Outlook
2000 Address book. It determines what accounts are listed
when the address book is first opened.

(& (mailnickname=*) (| (&(objectCategory=person)
(objectClass=user)(!(homeMDB=*))(!
(msExchHomeServerName=*)))(&(objectCategory=person)
(objectClass=user)(|(homeMDB=*)(msExchHomeServerName=*)))(&
(objectCategory=person)(objectClass=contact))
(objectCategory=group)(objectCategory=publicFolder) ))

I would like to modify that filter to include a number of
custom accounts.

Does Outlook/Exchange 2K even allow the filters to be
changed and, if so, Where is the query stored and How can
I replace it?
