Outlook No, Socket Error: 10060, Error Number: 0x800CCC0E


Error: The connection to the server has failed. Account: 'youraccount', Server: 'mail.yourdomain.com', Protocol: SMTP, Port: 25, Secure(SSL): No, Socket Error: 10060, Error Number: 0x800CCC0E


You can try the following :

1. The Outgoing (SMTP) server requires authentication. 

If you are using Outlook Express you should check the box 'My server requires authentication'. 


2. If you are behind a firewall, we may be unable to authenticate you. 

If you have a personal firewall, try lowering the security or disabling it to see if it is causing the issue. 

(Remember to re-enable it after testing) 


3. Your SMTP (outgoing mail server) could be blocked. 


Here is how to test it: 

A. Go to Start -> Run -> type: cmd 

B. When the Command prompt appears type: telnet mail.yourdomain.com 25

(include the spaces exactly as shown above and yourdomain.com is the domain you are trying to configure email account of. i.e. mail.econs.net) 

C. Wait a few seconds. You should see the following: '220 win1.econs.net ESMTP' for Windows server and '220-l1.econs.net ESMTP' for Linux server. This means that it is not blocked. 

D. If you do not see this message, your SMTP is being blocked.
