Hi, all
I have an Exchange 2007 environment with 2 Hub/Cas, 2 Mailbox, 2 Edge, now I have deployed Exchange 2013 environment in a new AD Site with 4 Frontend, 4 Backend, 2 Exchange 2010 Edge. I can send and receive email from my Exchange 2013 mailbox, but when I check the message header in my internet mailbox, I find that the message is routed from my Exchange 2013 Backend, then to Exchange 2007 Hub, then to Exchange 2007 Edge, then to my internet mailbox. I have made the edgescription on my Exchange 2013 Backend to Exchange 2010 Edge successfully. Why not the message send from my Exchange 2013 Backend to my Exchange 2010 Edge, then to the internet? How can I make that happen? Or it only happens after I uninstall Exchange server2007?
Thank you!
