A Windows Live Mail 0x800CCC18 error usually occurs in Outlook 2010 when your email account is configured for secure password authentication (SPA). The telecommunications server is not configured for this type of connection.
If you receive this error message that appears when checking your e-mail with a program like Windows Mail, secure password authentication may be enabled in your e-mail and authentication settings. Secure passwords may not be supported. If you are using Windows Mail, you can find your current email account settings by clicking on the Tools menu and selecting Accounts. To resolve this issue, open the email properties for your account and uncheck the “Securely check your password” box. Save your changes and go ahead.
This error message is usually displayed when your email stops working.
- Due to incorrect settings in your account.
- Incorrectly configured system files in your operating system.
- It can also be caused by viruses, adware/spyware attacks or wrong computer shutdown.
Updating Microsoft software would enable secure password authentication in many email clients, including various versions of Outlook Express and Windows Live Mail.

Disable Windows Live Mail Secure Password Authentication
This issue appears to be due to strong password validation in Windows Live Mail (and Outlook). Since this is an enterprise feature, it can cause problems on many computers that do not use this feature. Therefore, disabling this feature should fix the problem.
- Open Windows Live Mail and click Tools as shown below. After that click on “Accounts”.
- In the Accounts section, click the Properties button. In the Properties menu, go to the Server tab.
- On the Server tab, clear the Secure Password Verification check box and click OK to save your changes.
Use System Restore
Fortunately, Windows 10 offers the following tools: System Restore and Factory Restore, utilities that make it easy to reboot and update your computer.
Here’s how to restore and reset Windows 10.
- Open Start (or press Windows key + I to open Settings) and enter restore point in the search box.
- Click the appropriate result, select the drive where you want to store the restore point (usually the system drive), and click Configure> Turn On System Protection. This action will activate the System Restore feature.
- You must also specify the maximum disk usage allocated for disk space usage. Drag the slider to select the amount of space to select. Click OK to confirm.
- Now you can create a restore point. So, click “Create”, give it a name and click “OK”.
- System protection software creates a restore point that you can return to later by clicking the System Restore button. When you use the wizard, your previous status will be restored.
- You may need to take a few minutes to see what will be affected so you can reinstall the software and hopefully avoid all the applications that caused the problem that forced you to use System Restore.
Hopefully, this solution will help you fix the Outlook error code faster and prevent it from happening again.
