Read time 3 minutes

Outlook Express, a lightweight and efficient email application, was available in Windows up to the Vista version, subsequently replaced by Windows Mail. If you’re a Windows Vista user, you likely find it straightforward to access your default account. However, on rare occasions, an authentication error may surface.

0x800CCC00 LOAD SICILY FAILED – Authentication did not load

Reason:

• The first possible reason behind this error message is the user name and password you provided while signing in to your Outlook Express account did not match with the user name and password stored in the database.
• Another reason for the specified error message can be the corruption of the user’s account due to which Outlook Express cannot authenticate your identity and generates the above-mentioned error message

Restarting & Resetting the application

You can readily resolve the issue by following these steps:

• Exit and restart Outlook Express.
• Reboot your system and launch the application.
• Check the server status.
• If you still face the same error message then wait for 20-30 minutes and let the server reset your account. After the specified period, try again.
• In case, Outlook Express still displays the same error, create a new user account, add the same connection or login details, and verify if it works.

Note: Outlook Express users can also attempt to create a secondary identity as a potential solution to resolve the issue.

Most of the time, the described problem can be resolved by following the mentioned steps. Users can also explore other built-in solutions such as running a system scan with updated antivirus software, clearing junk or temporary files using the Disk Clean Up feature, updating system drivers, or reinstalling the email client application.

However, if the issue persists despite attempting the recommended solutions, you may find yourself in a critical situation.
