To begin using your custom domain in your accounts, it must first be requested for use in your enterprise.

To Request a Domain:

    1)  In the Enterprise Preferences, click Email Domains and Aliases.

    2)  Request Domain

    3)  Enter the domain name you wish to add.  You may use Check availability to ensure that it is not already in use.

    4)  Send Request and the domain will be verified for ownership and validity.  Once it is approved, (requests are generally processed by the end of the business day) you may add aliases to your users. 

    5)  Follow the same process for each additional domain you add.
