Due to the renaming of our company, I need to change everyone's email address to reflect the change.
Our current internal domain name is the same as our current internet domain. I've been searching around for the best answer as to how to facilitate this. I'm not sure weather I need to create an additional domain, a new forrest and domain, or if there's a way around all that. I've read up on a solution from the Exchange section that discusses a change to the Recipient Policies, but I don't think that will cover both the sending, AND recieving of mail. Thanks.
