The Windows Live Mail error 0x800CCC18 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, which appears when you check your emails with a program such as Windows Mail, secure password authentication may be enabled in your email settings and secure password authentication may not be supported. If you are using Windows Mail, you can find the settings for your current email account by clicking on the Tools menu option, then on Accounts. To solve the problem, open the email properties of your account and clear the Secure Password Authentication check box. Save your changes and let’s go.
This error message usually appears when your email is no longer working.
Due to incorrect settings in your account
Incorrectly configured system files in your operating system.
It can also be caused if your computer is affected by a virus or adware/spyware attack or an inappropriate computer shutdown.
Troubleshooting Error 0x800CCC18 with the use of these methods:
Step 1: Work with the Administrator area
To fix this error, users must first navigate to “Start Exchange Server Administrator” and continue.

The next step is to select the “Protocol” object, then open the POP3 protocol, which you can easily find in the right pane.
Step 3: Managing the authentication process

Now tap on the “Enable protocol” checkbox.
Go to the Authentication icon, then select an authentication process from the two specified authentication methods, which are as follows:

In Accounts, go to Properties and access the Server tab.

Use System Restore
System recovery allows you to customize your computer’s system files to a configuration that existed at a specific time. No personal data such as emails, documents or photos are lost.
Microsoft System Restore is enabled by default on most, if not all, HP computers shipped with Windows 7. However, Microsoft System Restore can be disabled and can cause problems if you try to restore from an earlier date. To ensure that system recovery is enabled, follow the steps below:
Click Start, right-click on Computer, then select Properties. The system window appears.
Click on System Protection on the left side of the system window. The System Properties window appears and the System Protection tab is active.
In the center of the System Properties window, make sure that System Restore is enabled.
I hope this solution will help you resolve the Outlook error code faster and that it will not happen again.
