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.

  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.
