To change the Exchange alias and mailbox name on a user account

1. In Exchange Management Console, expand the Recipient Configuration node and then select the related Mailbox node.
2. Double-click the mailbox entry for the user with which you want to work.
3. On the General tab, the first text box sets the mailbox name. Change this text box if you’d
like the mailbox to have a different display name.
