The connection to the server has failed. Account ‘mail.yourdomain.com’, Server: ‘mail.yourdomain.com’, Protocol: SMTP, Port: 25, Secure(SSL): No, Socket Error: 10051, Error Number: 0x800CCC0E. I am getting this error message. What can I do ?
If you have not changed anything since the last time you checked / sent mail, do not adjust your settings simply close Outlook Express, reopen it and try again later.
In windows XP try resetting the TCP/IP stack, by:
* Clicking on Start then Run then type in cmd
* On the screen which opens, type in netsh int ip reset c:\resetlog.txt
If this has not resolved your problem you need to check your Outlook Express settings, making sure that the POP3 and SMTP servers are correct.
Next, ensure port 25 for SMTP is not blocked by your LAN, proxy, firewall or Internet Service provider. This is a very common scenario where an ISP blocks outgoing port 25 access to third party SMTP server for their customers.
You can workaround that by changing to port 26 by following the third demo video set at
If you are still unable to send, ensure outgoing SMTP authentication is enabled. If that also fails, you would need to check with your ISP if they are blocking third party SMTP servers and ask them for the SMTP server you should use.
You can configure by following tutorial 3 at http://www.nettigritty.com/support/hosting/tutorials/cpaneltutorials.php
If you’re still having problems, it could be that Outlook Express is itself corrupt. You may need to uninstall and reinstall it.
