In our organization we have a forest that contains one domain and one sub domain. We are in the process of moving all users/objects from the subdomain to the parent domain. We have exchange mailboxes for both domains. Do we need to make any changes to our exchange servers or will this change not affect exchange? Thanks

Clarify: You want to know if its ok to migrate user objects to parent domain without moving mailbox in the child domain, right? Per my testing on the lab, after migrated user account to parent domain, outlook can be open normally and mail flow perform works without malfunction Im using ADMT v3.0 My lab: parent domain + one child domain OS: Windows Server 2003 SP2 + Exchange Server 2003 SP2
