Exchange 2010 mail routing to 2007 server
Posted on 2014-01-16
Good Morning experts,
We are currently in a co-existence phase that I would like to wrap up and have gone from Exchange 2007 to 2010.
Almost all mailboxes have been successfully moved.
Certs are installed and working properly
Our firewall and spam filter rules have been changed and are all pointing to the new exchange server.
The mx record is still currently pointing to the old exchange server.
I have the checklist from Microsoft for the remaining tasks.
Here is my question.
I have the hub Transport role and smtp recievers created on the new server but mail is still routing to and from the old exchange server?
Is the mx record the reason this is still happening, or does this not route though the new one until I fully decommission the old one?
Any assistance is appreciated.
