Exchange server 2013 in Windows server 2012 VM
It was working fine then start the issue.
Firewall is managed externally and the last report said:
"I checked the firewall logs, which shows traffic being allowed through port 25 from 10.10.10.10 to 4.28.237.225: Log Number 116 Last Activity 2014-08-28 23:48:33 Status [accept] Src 10.10.10.10 Dst 4.28.237.225 Service SMTP Policy ID 1 Src Port 64081 Dst Port 25 While I showed one log, there were multiple log entries showing the same: traffic being accepted through port 25 from 10.10.10.10 to 4.28.237.225.Can you verify that the mail server is set up so as to allow port 25? "
Today I was able to telnet the server from home: successfully

Also the receive - send connectors seems ok
Mx record point to Microsoft protection: dualtemp-com.mail.protection.outlook.com.
Again, OWA is able to access and send/receive emails internal but never external even no bounceback just it never arrive.
Help me please. This is my first admin chaos...
