How do we incorporate external recipients into our Global Address List (GAL)?
Exchange 2000 Server and Exchange Server 5.5 support addressable objects (i.e., objects to which you can send mail) that reside outside your Exchange organization. These objects can contain SMTP, X.400, or foreign email addresses and appear in the GAL just as regular mailboxes do. Users can select these objects from Outlook, Outlook Web Access (OWA), or Lightweight Directory Access Protocol (LDAP)—enabled clients. When you need to import many external recipients into your directory, the easiest solution is to use Exchange 5.5's Directory Import feature, although other ways exist. For example, you might use the LDAP Data Interchange Format Directory Exchange (LDIFDE) utility or custom Microsoft Active Directory Service Interfaces (ADSI) scripts. (For more information about Directory Import, see my Windows & .NET Magazine article "Super Export and Import Tools," http://www.winnetmag.com, InstantDoc ID 9074. For more information about using alternate methods, see Barb McDonald, "Bulk Object-Manipulation in Exchange 2000," April 2002, InstantDoc ID 24129.)
