We are at a point in an E2K3 to E2K7 migration where we are attempting verify email flow
between the two servers. I can send email out from the E2K7 server to anyone internally
or on the Internet, however I can not send an email from someone on the E2K3 server
to someone on the E2K7 server. Looking at the queue on the E2K3 server, they are held
up on the E2K3-E2K7 routing connector queue.
The Authentication tab on the Receive Connector on the Hub Transport are set for Basic,
Exchange Server authentication, and Integrated authentication, with the permission groups
set for Anonymous users, Exchange users, Exchange servers and Legacy Exchange Servers.
Am wondering what I am missing here in getting the two server to communicate fully?
