Mailbox Creation Exchange 2010

I have an AD forest in my company with a sub domain. Top level domain is "". The sub domain is "".

Our exchange keeps the mailboxes for both domains. The email addresses are below.

i have added "" & "" as accepted domains in our exchange but the problem is every time I create an user mailbox SMTP address comes only as "".

I would like to know how to get all the SMTP addresses in the mailbox in relation to the accepted domains I have configured in the Exchange Server.

Hope I have made myself clear here.

Expert help is much appreciated.

Adding a note: only one of this email address can be principal and outgoing email address. Principal mail address is the address appearing as user´s mail address, can receive from other directions but outgoing mail appears send as principal address.
