Error 0x800CCC0D/E

You may get one of the following error messages:

  • The connection to the server has failed. Account: '', Server: '', Protocol: POP3, Port: 110, Secure(SSL): No, Socket Error: 10061, Error Number: 0x800CCC0E

  • The host '' could not be found. Please verify that you have entered server name correctly. Account:'yourname', Server '; protocol: POP3, Port:110'Secure(SSL):No, Socket Error:11001,Error Number 0x800CCC0D.

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.

If this has not resolved your problem you need to check your Outlook Express settings, making sure that the POP3/SMTP servers and your email username/password are correct.

Then test your connection by following this procedure:

  1. Click the "Start button" then click on "RUN". Type "cmd" on (Windows NT/2000/XP) or Command (Windows 95/98/ME), this will open a new command prompt window with white text on a black screen.

  2. Type in the following replacing "" with your actual domain name:

    • telnet 110 and then press Enter on your keyboard. You will then be connected to the email server.

    • Type in USER followed by your email address e.g. USER [email protected] and then press Enter. You will then get a message +OK Please enter your pass, with the PASS command.

    • Type in PASS followed by your password e.g. PASS password and press Enter. If it is correct, you will get an OK Well done message.

    If you can do this, you have connected to the mail server and so the problem lies somewhere within Outlook.

  3. If you can't get in this way either, it could be that your password has somehow become corrupted. Try changing it in My Account. Try again.

  4. If this does not resolve your problem are you running anti virus software or firewalls? If so disable them and try again. If the problem has vanished, configuration of these products could be the problem, particularly if they are set to automatically scan incoming and outgoing email.

    NOTE: Windows XP has a firewall built into the operating system which you can disable by selecting there too and try again.

The basic checks have now been completed. If you are still getting this error message, there are two more drastic options to try.

The first is to reinstall TCP/IP from scratch in case this component of Windows has somehow become corrupted. To do this click on the Start menu and then enter your Control Panel. Next double click the Internet Options icon and select the Connections tab. From here you should be able to identify your connection which you need to select and then click on Settings followed by Properties and select the Advanced tab. Here the checkbox for the Internet Connection Firewall should be unchecked to test whether it is causing this problem.

If this does not resolve the problem in windows XP try resetting the TCP/IP stack, by:

  1. Clicking on Start then Run then type in cmd

  2. On the screen which opens, type in netsh int ip reset c:\resetlog.txt

If you're still having problems, it could be that Outlook Express is itself corrupt. Microsoft's Instructions on how to delete it and reinstall it, along with making a backup of your address books etc, are located here.
