Hi,

     I am facing problem that, in my organization we are using Exchange  Server 2013. We are facing

problem that we are getting emails lately ( Delay ). While observing emails stuck in Queue & give  Exchange Server 2013: Failed to connect. Winsock error code: 10060 error. After 30 minuts it connects automatically. But again error occurs after some time. Please help me to solve this issue  

Hi

Can you remove the send connector and re-create it?

Are you able to telnet on port 25 when the above happens?

How are you routing your mail? DNS or Smarthost?

Hi,

Add information to the suggestions above, I suggest to enable Protocol logging on send connector to diagnose mail flow problems.
