I have recently setup an additional domain controller at a remote site, I have also setup a secondary Exchange Server down there. I have setup two sites in the Active Directory using the same domain.
I have moved over one mailbox from the primary Exchange server at site 1 to the secondary Exchange server at site 2 to test that it is working ok. I want users to login to their mailboxs locally and not accross the VPN (which is slow!), Now at first when I had various DNS issues I was unable to login to Outlook on the client machine who's mailbox I'd moved. After resolving some DNS probs I was then able to login, but was not able to send and receive mail. I would receive the following error:
"The e-mail system was unable to deliver the message, but did not report a specific reason."
I then continued looking into this... I added the second Exchange server under Administrative Groups, First Administrative Group, Routing Groups, Connectors, (my connector) and Local Bridgeheads; as it wasn't already there. I can now send and receive external emails from my Hotmail test account. (I dont have a solid understanding of what a Local Bridgehead is however).
I have one last problem, I cant send internal emails on the mailbox I moved to the new server. I can receive internal emails, but not reply or send. I dont get any failed receipt or error message.
I'm no expert on exchange so it may well be something I haven't configured correctly or missed.
Any help on this is much appreciated.
