Outlook Error 0x800ccc0d is simply a failure to connect- that's in the error message. How to fix this error is however dependent on how correct your account settings are.
In Outlook Express, you will see an error message much like this:
If you have more than one account, you may see multiple items in the list. Click on the one with which you are having trouble and click on Properties. In the resulting dialog box, click on the Servers tab and you should be able to see your server settings.
If the Incoming Mail (POP3) setting is incorrect, then obviously you get the error 0x800ccc0d. You can verify your account server settings from your ISP vendor or from the provider of your e-mail account that has been configured in your e-mail client. Say, if you are accessing e-mail via Yahoo!, you need to ask the Yahoo help desk for your server settings. Once this is known, you can change your incorrect settings or re-configure your e-mail account again.
Additionally, while accessing your e-mail make sure that you are connected to the Internet. This error may also occur because you are not connected to the Internet at all. If your Internet connection is not working, that has nothing to do with Outlook, Outlook Express or error 0x800ccc0d. Your mail failure is just one symptom of not being connected to the internet.
Another possibility of receiving such error is that your mail server may simply be down. Your ISP may have changed mail servers or may have incurred some technical problems. In such case, you need to contact your ISP to determine whether or not they have an alternative mail server that you can use, or perhaps how long you might need to wait for things to be fixed!
An alternative to all the resolutions can be to refer to remote computer support professionals who can solve your Outlook errors on laptops, PC, desktops, or home computers. Sometimes, solving problems on your own, may cause a change in the normal settings of your PC/Outlook or may further damage the issue. That's why you can get your PC or laptop checked by technicians and then seek technical troubleshooting on Outlook errors.
