Since I create a receive connector on Microsoft Exchange 2013 so another computer relay email to the exchange server I keep having problems with the Transport services that get stuck on starting. As soon as I disable that connector the service start and if I enable it back it still work until the server get reboot it.
This is what I see on the event Viewer:
Inbound direct trust authentication failed for certificate %1. The source IP address of the server that tried to authenticate to Microsoft Exchange is [%2]. Make sure EdgeSync is running properly.
The address is already in use. Binding: 0.0.0.0:25.
Failed to start listening (Error: 10048). Binding: 0.0.0.0:25.
