I have an Exchange 2007 server on the internal network running the Hub Transport, Client Access and Mailbox server roles. I also have an Edge Transport server on the perimeter network, subscribed with the Hub Transport server role. Email flow is fine, but I cannot get Outlook Web Access (OWA) and Office Activation Wizard (OAW) to work through the Edge Transport server. Is there some kind of pass-through mechanism that forwards OWA and OAW requests to the Hub Transport server from the Edge Transport server? Or does this require extra configuration work?
