Email Address Policies
Applies to: Exchange Server 2013
Recipients (which include users, resources, contacts, and groups) are any mail-enabled object in Active Directory to which Microsoft Exchange can deliver or route messages. For a recipient to send or receive email messages, the recipient must have an email address. Email address policies generate the primary and secondary email addresses for your recipients so they can receive and send email.
By default, Exchange contains an email address policy for every mail-enabled user. This default policy specifies the recipient's alias as the local part of the email address and uses the default accepted domain.
The local part of an email address is the name that appears before the at sign (@). However, you can change how your recipients' email addresses will display. For example, you can specify that the addresses display as [email protected].

Configure an Accepted Domain within Your Exchange Organization as Authoritative Applies to: Exchange Server 2013 If a domain belonging to your organization hosts mailboxes for all the recipients within an SMTP namespace, that domain is considered to be authoritative.
By default, one accepted domain is configured as authoritative for the Exchange organization.
If your organization has more than one SMTP namespace, you can configure more than one accepted domain as authoritative.
