Coexisting Exchange 2010 and 2003, users on 2010 can receive but cannot send
Posted on 2010-04-10
I Tried searching a lot and tried different settings only to mess up my current server......
Have an Exchange 2003 server. Works great and all email boxes are on that server.
Installed Exchange 2010 on another server,during install, it connected to the 2003 server and bought in all settings from that server. I moved 1 mailbox to 2010 and used Outlook 2003 to connect to it, can receive emails but cannot send internal or external.
I saw that no Send Connecter was created, I guess since it is a coexisting server and the 2003 server is sending emails out BUT i still created one with NO smart host (and later WITH smart host pointing to the 2003 IP checking with all the Authentications)
When I did that all emails for ALL USERS were going to the 2010 server and sitting in the "unreachable" folder. After I deleted this send connector and rebooted the server, emails for all users were going to the 2003 queue
I read about this intra-organization Send connector that should be there but i cannot find it or dont know where it should be.
So I am stummped, all help would be much appreciated
