This topic explains how to use the Exchange Management Console and the Exchange Management Shell to create a mail-enabled user in Microsoft Exchange Server 2007. This procedure creates a new user object in the Active Directory directory service, and then mail-enables the user object.

A mail-enabled user has an e-mail address at the organization but does not have an Exchange mailbox. All e-mail messages that are sent to the mail-enabled user are forwarded to the specified external e-mail address.

To perform this procedure, the account you use must be delegated the following:

  • Exchange Recipient Administrator role

  • Account Operator role for the applicable Active Directory containers

For more information about permissions, delegating roles, and the rights that are required to administer Exchange Server 2007, see Permission Considerations.

If you want to create a new mail user in a domain that is different than the one in which your Exchange servers reside, you must first prepare that domain for Exchange 2007. To learn more about preparing a domain for Exchange 2007, see How to Prepare Active Directory and Domains.

  1. In the Exchange Management Console, click Recipient Configuration.

  2. In the action pane, click New Mail User. The New Mail User wizard appears.

  3. On the Introduction page, click New User, and then click Next.

  4. On the User Information page, complete the following fields:

    • Organizational unit   The default value of this field depends on the Recipient Scope set in the Recipient Configuration node. If the recipient scope is set to the forest, the default value is set to the Users container in the Active Directory domain that contains the computer on which the Exchange Management Console is running. If the recipient scope is set to a specific domain, the Users container in that domain is selected by default. If the recipient scope is set to a specific organizational unit (OU), that OU is selected by default. To change the default OU, click Browse, and then select the OU you want.

    • First name   Type the first name of the user. This field is optional.

    • Initials   Type the initials of the user. This field is optional.

    • Last name   Type the last name of the user. This field is optional.

    • Name   By default, this field is populated with the user's first name, initials, and last name. You can modify the name in this field. This field is required.

    • User logon name (User Principal Name)   Type the name that the user will use to log on to the domain. The user logon name consists of a user name and a suffix. Typically, the suffix is the domain name in which the user account resides. This field is required.

    • User logon name (pre-Windows 2000)   Type the user name for the user that is compatible with the legacy versions of Microsoft Windows (prior to the release of Windows 2000 Server). This field is automatically populated based on the User logon name (User Principal Name) field. This field is required.

    • Password   Type the password that the user must use to log on to the domain.

    • Confirm password   Confirm the password that you entered in the Password field.

    • User must change password at next logon   Select this check box if you want to require the user to create a new password at first logon.

  5. Click Next.

  6. On the Mail Settings page, complete the following fields:

    • Alias   By default, the alias is the first name, initials, and last name of the contact, separated by underscore characters (_). You can modify this field.

    • External e-mail address   To specify the external e-mail address, perform one of the following tasks:

      To specify a Simple Mail Transfer Protocol (SMTP) e-mail address, click Edit, and then in E-mail address, type the SMTP e-mail address.

      To specify a custom e-mail address, click the arrow next to Edit, click Custom Address, and then in E-mail address, type the e-mail address and the e-mail type. For example, you can specify an X.400, GroupWise, or Lotus Notes address.

  7. Click Next.

  8. On the New Mail User page, review the configuration summary, which contains information about the options that you selected for the new mail user. To make changes, click Back. To create the new mail user, click New.

  9. On the Completion page, the summary states whether the mail-enabled user was successfully created. The summary also displays the Exchange Management Shell command that was used to create the new mail-enabled user.

  10. Click Finish to complete the task.

  • Run the following command:

    New-MailUser -Name Ted -FirstName Ted -LastName Bremer -ExternalEmailAddress -UserPrincipalName -OrganizationalUnit

    The Exchange Management Shell will prompt you to enter a password for the user.

For detailed syntax and parameter information, see the New-MailUser reference topic.
