Microsoft Windows uses error codes when something goes wrong. These codes can then be used to find out what is wrong with the computer. If you use Microsoft Outlook, Outlook Express or Windows Mail, then you might see error number 0x800CCC0E.
This type of error only exists when using one of these email programs, and tends to appear if there is a problem when sending mail. Mostly, it indicates a problem with the SMTP service. SMTP (which stands for Simple Mail Transfer Protocol) is the service responsible for sending emails from your computer to the Internet.
If this process is interrupted or your computer cannot find a server to send the email to, you may see a 0x800CCC0E error.
The best way to avoid seeing this error is to make sure your Internet settings are correct. You can find your email settings in Microsoft Outlook, Outlook Express or Windows Mail very easily, and you should check to make sure they match the settings given to you by your email provider.
Be sure to be very precise when checking these details, even one character out of place can cause an error.
One thing to check is that your SMTP port is set to port 25. Unless your email provider has told you otherwise, all email usually gets sent to the Internet on port 25.
You might also want to make sure the name of the mail server is correct. Usually this will be the name of a mail server such as smtp.yourisp.com or a series of numbers called an IP number.
Another common reason why you may see this message is if your email program is being blocked by a firewall or anti-virus program. Ask yourself if you’ve installed such a program recently. Even if you haven’t your existing firewall may have been updated and is now blocking your email program.
To test this, find out how to disable your firewall.
Don’t worry about viruses and intruders; you will only be disabling it long enough to see if you can send email properly with it disabled. Turn it off briefly and try to send and email. If you are successful, then you have found the problem. Turn your firewall back on and send and email.
If you receive the same error message as before, you have confirmed the problem. You now have to find out how to program your firewall to allow email through. Most firewalls and anti-virus programs make this easy, but you may have to read the instructions to find out.
