Managing Mail Contacts and Mail Users

 

Applies to: Exchange Server 2007 SP3, Exchange Server 2007 SP2, Exchange Server 2007 SP1, Exchange Server 2007

Mail contacts are mail-enabled Active Directory directory service objects that contain information about people or organizations that exist outside your Exchange organization. Mail contacts are ideal for representing people external to your Exchange organization who do not need access to any internal resources.

Mail users are similar to mail contacts. Both have external e-mail addresses, contain information about people outside your Exchange organization, and can be displayed in the GAL and other address lists. However, unlike a mail contact, mail users have Active Directory logon credentials and can access resources to which they are granted permission. If a person external to your organization requires access to resources on your network, you should create a mail user instead of a mail contact.

To learn more about mail contacts and mail users, see Understanding Recipients.

This topic lists the management tasks that you can perform for mail contacts and mail users, and includes links to topics that will help you complete the tasks. Unless otherwise noted, these tasks can be performed by using the Exchange Management Console or the Exchange Management Shell.

There are two types of mail contacts in Exchange 2007: mail contacts and mail forest contacts. Mail forest contacts are read-only recipient objects that are updated only through Microsoft Identity Integration Server (MIIS) or a similar custom synchronization. You cannot remove or modify a mail forest contact by using the Exchange Management Console or the Exchange Management Shell.
