User joined domain but cannot get e-mail

[Johnny Rio]

I joined a user on my network to a new domain (Windows 2003 Server network)
and now she cannot receive her e-mail. Since she has a local account and
domain account [(MooreA - local account) and (MooreA.Domain - network
account)], I figure Outlook needs to import (?) her e-mail account
information to her new network user account so that she can get her e-mail
while logged on the network? As it is now, she has to log on locally on her
PC to get e-mail. I would like for her to be able to get her e-mail while
logged on the domain. Is this an easy fix?

Thanks,
Johnny
