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 server running Active Directory, which is Outlook can access with its LDAP service. See Shared address book with Active Directory.
- A web-based contact list with a synchronization feature
The add-ins on this page operate as MAPI service providers and, therefore, generally do not work with Microsoft Outlook 98 or Outlook 2000 in Internet Mail Only mode. There are exceptions, however.
