Hi,
I have successfully upgraded Exchange from 2007 to 2010 on a new server. Exhange 2007 still excist on the Server 2008 which is also domain controller.
I am able to sent from the 2010 server but when i point my router to receive port 25 smtp traffic i get the message ‘Your message wasn’t delivered because of security policies’ . It still works on the old 2007 server, looks like the transport service is stilll being used, when i stop this service on the 2007 there is no traffic.
On both 2007 and 2010 no Distribution Group has been configured.
I’d like to deinstall the 2007 server but i am affraid i have missed something in the transmission to 2010.
Can someone please advise?
thanks,
Boris
