I'm looking for some suggestions to do exchange troubleshooting when it doesn't work. Currently I am unable to send, but I am still receiving. It is not a network related issue as Exchange seems to use the same connection to send/receive and I've checked the firewall and nothing is being blocked and netstat is showing the connection as established on both ends.
