I am trying to find the best way that 4 users in my organization can share a
contact list without other users in the organization seeing this contact
list. We are using Exchange Server 2003 and Outlook 2002 and Outlook 2003. We
also have Mac users using Office 2004 and Office X but we don't want them to
be able to see these specific contacts.

I know that we can create a public folder and that the 4 users can import
the contacts of that specific public folder into their Outlook Address book
so that they can send an email to one of those contacts. However, will these
contacts automatically be updated in each user's Address book if there is a
change and is there a way to hide that public folder from the rest of the
organization? If anyone can shed light on this for me, I would greatly
appreciate it.

Thanks!
