Exchange 2010 not able to transport emails to Exchange 2007
Hi,
That's probably an easy one but I'm stuck and can't figure it out. So i'm calling on the real exchange guru out there. I installed exchange 2010 over the week-end to work with our exchange 2007 server. Install went well and I moved my mailbox from 2007 to 2010. Now here is the issue and it only affect my accout since I have the only mailbox on the 2010 server.
I can receive emails from internal users (Exchange 2007) and from external users. I can send emails to external users but I cannot send anything to any of the 2007 exchange users.
My messages get stuck on the queue "SMTP relay in active directory site". And the full error is: 451 4.4.0 Primary target IP address responded with: "421 4.4.2 Connection dropped due to ConnectionReset.". Attempted failover.....
I am not sure if that has to do with certificates or not. The 2007 exchange has a Valid CA certificate while exchange 2010 has a self signed certificate... I will get a valid one soon for the transition time. But i'd like to get the 2010 server to talk to the 2007
Thank!

Yes, same site and same phisical location. Both servers have same roles: Hub transport, Client Access, Mailbox.
this is typically when there is a firewall between both servers is this ur case?
ASKER
Nope, Both servers firewall service are set to disable on the service tab and I verified that it was not running on both servers.

Question. When I upgraded my exchange 2007 to SP2 as required before been able to install 2010, it made me remove the SMTP server option (from the add remove program applet). Do i need to re-enable it back to be able to receive SMTP mail from the exchange 2010? I would not think so since I am able to receive emails from outside but just wondering after the mail troubleshooter told me it could not connect to the port 587...

Ok, it's fixed now. While trying to get a SSL cert working on my 2010 this morning, I invalidated the certificate that was on 2007. I did import the new one that was generated later on this morning and even though I did not get OWA to work again, I now can receive emails from users on the 2007 exchange server and also send to them as well... Still need to figure out the OWA part on the 2007 server but I'm sure i'll be able to get to it
what is the issue with OWA ?

Now that I played around with the certificate on the main exchange server. Even after re-importing the correct SSL certificate, when I enable SSL on the https://server/owa I guet a page not found error... not even a "this webpage requires encryption", just page could not be displayed. When I turn off encryption and access the same page using http instead of https, then no issues and it works fine. I left it like that now but want to fix it asap because there is no security right now...
