Hello Experts
I have One Exchange Server that is working fine . I wanted to install a Second Exchange Server which i did . every thing was working fine when 3hours after the Installation of the Second server a user reported that he got a message from MicrosoftExchange329e71ec88ae4615bbc36ab6ce41109e@mydomain.com about a message not going trough . I wonder if the sending problem is not related to the Installation of the Second server

Adding a second exchange server is not related to your mailflow problem.

I'd check the queues on both server. Also, make sure that SMTP (TCP25) are opened from new server to smart host or internet if it sends out directly. is new server added to send connector.

also - error message: Was the undelivered message internal or external?
any info in error message?

Hello

For the moment I want to keep that server there because i want to migrate to it . I did not change Exchange configuration (Connectors) . Should I ?

the new server is also EX2010?
out-of-the box the servers can send and receive email other servers internally, but to be able to accept email from WAN an EX2010 need an anonymous receive connector receiving emails from internet, and the send connector need to have the new server added to source server to be able to send message.

can you elaborate on error message?
