I have domainA which already has exchange 2007 integrated into it. I have domainB which was added many years after domainA but is in the same forest. I have a two way trust setup between the two domains.
Do I simply run the Setup.com /PrepareDomain:domainB of target domain to be prepped? The issue is that Exchange 2007 does not see domainB at all. So I would basically have to have an account for email setup for end user in domainA and then have the user logon account in domainB.
Do I run this from exchange server in domainA or do I run this from one of the domain controllers in domainB?
Any help would be greatly appreciated as I'm familiar with exchange in a single domain environment, but never had a multi-domain environment.
