I have a setup using Exchange 2003 where some of the users are on the Exchange server and some are not and they share a single domain name. I am trying to do this on 2007 and it is not working out the way we want.
MS changed the whole thing in 2007 compared to 2003 and I can't figure out the combination of Edge server sending policies to make it right. I would like to have all emails looked up outside the server and then delivered. Since the SBS server grabs the mail on the external email server, the external routing is fine, but the internal routing would need to be external in all cases.Here is a simple example:
For example Bob is an in-house employee and is in the office using Outlook. Joe is a contractor or a remote user who does not need exchange access so he is going to an external email server, not exchange. When Bob sends to Joe it fails as AD does not find the user. I have looked for the answer and have no success in implementing it. There is a process for Exchange to check AD, then if the user is not found send out to the world to see fit ere is a match
This is a SBS 2008 box with Exchange 2007
