How Do I Fix Error 0x800CCC90 On Windows Live Mail

The error code 0x8000ccc90 means that Windows Live Mail received an invalid response from  the POP3 server. This could be an issue with your mailserver or with the mail client itself if it is corrupt. Many people who asked this question on getting around with this particular error code are left scratching their heads because it’s not confirm where the issue/error is originating from.

However, i have successfully resolved this issue in the past but there is not a single method with which you’d be able to fix it so you will have to follow all steps if one doesn’t work, move on to the next one.

Without talking any further, let’s get started!

Step one is to make sure what your account settings are if  they are up to date. The easiest way to do this is to call your ISP and get the settings mailed to you  or have them written down (i prefer mail to avoid human error) – You’ll still be able to access your e-mails by getting into the webmail.

If you do not know how to get into webmail, go to and type “isp name + webmail”, eg: comcast webmail

The way i find the settings is by entering them on Thunderbird and it picks up the settings itself by calling it’s database.

Step two is to confirm your mail account settings in Windows Live Mail by opening your account properties and matching them with the settings you’ve received.  Check your Windows Live Mail settings, by going to the Accounts tab and selecting Properties. Make sure that the servers (incoming and outgoing) + the port numbers / SSL are correct. Check if issue is fixed now! if not, then

Step three would be to uninstall and reinstall Windows Live Mail, but before you do this make sure you backup your emails, contacts etc. by Exporting from the File Menu so you can import it later after reinstalling Windows Live Mail. To uninstall go to Control Panel -> Programs & Features -> Uninstall a Program – locate Windows Essentials and double click on it then select Remove one or more programs, select Windows Live Mail and uninstall it.

Once it is uninstalled, Click Here to download essentials and update to the latest version of WLM. Once it is re-installed, open and reconfigure the client then import the mails if you saved them earlier.

Personally, i am not a fan of Windows Live Mail due to the limited support and number of errors – if you were to ask me which client i’d recommend then it’s Thunderbird.
