Hi, I have single forest and multiple child domain (child1 and child2). Currently, all exchange servers are in child1 domain. Is it possible to install new set of exchange servers in child2 domain without using GAL segmentation (part of the feature in exchange 2010 SP2)? And yet they don't see each other in the GAL.

Yes, I have tested in my lab too.Kelvin Teang

Is it possible to hide all exchange server/Recipient/Mailbox from child1 and child2 via Exchange Management Console (EMC)? Exchange servers in child1 domain don't share same EMC with Child2. Thus, it shows all exchange servers (be it in child1 or child2) when I perform get-exchangeserver.Kelvin Teang
