Contacts are objects that serve as pointers to resources outside an Exchange organization. You can think of a contact as an alias that contains an address for that outside resource and rules for handling the transmission of messages. Whenever a user sends a message to a contact, Exchange Server forwards the message to the appropriate foreign messaging system. Contacts have many of the same attributes as mailboxes and can be viewed in the Global Address List.
To create a new contact, choose New Contact from the Action menu of Active Directory Users and Computers. This command opens the New Object—Contact dialog box (Figure 9-17). Enter a full name and a display name, much as you would for a typical user.
When you click Next, the dialog box shown in Figure 9-18 opens. Enter a display name in the Alias field, click Modify, and select the type of foreign address you want to create. If this seems like the same process you used to create a mail-enabled user previously, you are right. In fact, a contact is like a mail-enabled user that does not have the right to log on to the network. When you're done, click Next to display a summary page. Click Finish on the summary page to create the new contact.
