digitalnull Posted August 7, 2015 Share Posted August 7, 2015 Ok so I have inherited two domains, one domain runs active directory services that all of the workstations are joined to (domainA), the second domain hosts exchange (domainB). After signing in on a computer in domainA we have to authenticate outlook with domainB to get email. The end result, I would like is to be able to authenticate with domainA for email but have it load the profile as if it was domainB. I can create a one way trust from domainB to domainA but Im not sure how to fool exchange into believing DomainA\user1 is DomainB\user1. I've messed around with Authenticate as permissions on domainB but that doesnt seem to work correctly. I don’t want to mess with full access permissions on exchange as that would cause issues. I havent had any problems getting the trust functioning correctly, just the windows/exchange user side of things. Does anyone have any experience with this?

Muckrak Posted September 11, 2015 Share Posted September 11, 2015 You will be a 2 one way trust. A to B and B to A. You seem to have inherited a messy setup. My best recommendation would be to use ADMT and migrate everyone over domain B if that is a possible scenario in your case. Quote Link to comment Share on other sites More sharing options...
