Basically set up a New 2012 server, installed Enterprise Exchange 2013 and Migrated all Users into new Databases.
After restarting the Server, Transport Service would not start, removed two receive connectors.
ECP and OWA access work, but no mail flow and to be honest, though it was like 2010, Nope and now stuck.
The web or outlook client can connect but that's it, no mail flow
This is a new server, nothing added, just need to rebuild the communication fabric.
