create separate receive connector on exchange 2007 to receive email from exchange 2013. remove all authentications and select
Anonymous users only on receive connectors. assign Exchange 2013 as accept source. if Exchange 2013 Mailbox Server has any Other Exchange 2007 receive connectors, please remove the IP from there. keep exchange 2013
Mailbox Server IP for this receive connectors only. create send connector from exchange 2013 and sources server as exchange 2013 mailbox Server . configure target host as Exchange 2007 Servers.
check Ports are open from Firewall ( telnet from exchange 2013 Mailbox to Exchange 2007 HUB POrt 25 ), check whether Send connectors SMTP port is 25 (get-sendconnector -identity "Exc2013-to-exch2007" |fl
if u can telnet and send emails from exchange 2013 to exchange 2007, it should work .
make sure to restart Exchange transport Services on both Exchange 2007 HUB and Exchange 2013 Mailbox. might wait for 15 seconds :)
Could somebody please explain how I can do this. Basically I need a tutorial-level explanation of what I should be doing on each server. I have tried creating these connectors but I'm missing some finer details and I might end up breaking the existing Ex2007
environment.
So if you could explain in almost point form in a manner like this:
On Ex2007| Server Configuration| Hub Transport| send Connectors, create Coexistence send connector (then go through its settings)
And on Ex2013| EAC| Mail flow| Send Connectors, create ....
That would be much appreciated. My migration has been stalled for over two weeks because of this issue. And I'm planning on doing a few more at other sites.
