A feature of Microsoft Exchange Server that enables administrators to configure how e-mail aliases and other information are automatically generated when mailboxes are created. For example, using auto naming, you could automatically generate any of the following e-mail aliases for Jeff Smith’s mailbox:
You could also devise some other custom naming scheme. These e-mail aliases then would be combined with the Domain Name System (DNS) domain name of the Exchange organization to form the user’s standard e-mail address. For example, if the domain name of the company is northwind.microsoft.com, JSmith would be combined with it to form the e-mail address JSmith@northwind.microsoft.com.
