Microsoft Exchange Server provides a foundation for shared address lists through the global address list; enter outside addresses as custom recipients. If everyone is using Microsoft Outlook, you can also create public folders for sharing contacts.
If you don't have Exchange Server, beyond the tools listed below, you might consider using:
- An LDAP server -- especially if you have a Windows 2000 server running Active Directory, which is Outlook can access with its LDAP service. See Shared address book with Active Directory.
- Net Folders (Outlook 98 and Outlook 2000 only and not fully reliable)
- A web-based contact list with a synchronization feature
- Using the Briefcase to Share Microsoft Outlook Folders
These tools synchronize Outlook contacts folders with external databases. In effect, the database is the group contacts list, with the sync utility ensuring that Outlook has the latest data. Exchange Server is not required.
