Hi all. I have exchange2000 with Windows2000 Domain (diferents machines). I have a domain called company.com, and I have mail address called someone@xxxxxxxxxxxx To create a mail address, I just need add a username in Active Directory. Now I add another domain at DNS called enterprise.com (just DNS, not Active Directory). How I can just create mail address using @entreprise.com at Exchange without use AC? Thanks! Rafael Rodrigues.
