@dbeato said in Exchange - Different Domain, Same Forest Users:
If they are in the same forest it should not be an issue.
@dbeato , you're an Exchange guy right? Can I pick your brain a bit?
Should the NIC on the one Exchange server residing on the .org domain (the one I want to add the .net domain user mailboxes to) have the DNS set to prioritize .net before .org? What's the best practice here?
Additionally, the Exchange server in question (residing on .org), has the default Accepted Domain set to the .org domain, if I change that to the .net domain, is that going to throw a wrench in things or is that easily reversible? I don't have a full understanding of what could happen if I changed that, and I'm scared to try it at this juncture. Does my other Exchange server for the .org domain share this setting or is it specific to this server?
Some things I've tried so far:
Disable Global Catalogue on .net DC via Administrative Tools>AD Sites & Services>NTDS Setting>Properties. Reboot, re-enable.
Restarted Services>Microsoft Exchange Active Directory Topology on Exchange Server in question.
Get-ExchangeServer -Identity "<SERVERNAME>" -status | fl
shows .org Global Catalogue.
