Dear all
My setup is like this:
Edge transport in Parent domain, three exchange servers in parents domain, (2 = exch 2007 and 1= exch 2013) where the primary exchange 2007 has been migrated to 2013.
the connection between the Parent and Child is a VPN connection
In the child domain, I had one exchange which has been migrated to 2013.
Mail flow Issue:
I am able to send and receive email from internet to my parent domain with no problem through the edge running on exchange 2007 SP3 (all exchange server 2007 have SP3)
I am able to send email to internet via different ISP on the child domain, and am able to receive emails from internet to child domain via edge at the Parent domain.
I am able to send email from my parent domain to my child domain,
BUT
I am not able to send email from my child domain to my parent domain, they are all queuing on the exchange server 2013 on the child domain.
I need guidance on what could be blocking the mail from from the child domain to parent domain
Hope my explanation is clear,
Thanks Team in advance.
Regards
Michael
