How to Fix Error 0x800CCC0E on Outlook

If you’re carrying out a PC repair, follow the suggestions below to resolve the Windows 10/11 Outlook error 0x800CCC0E problem:

Check the internet connection

The main reason behind the Outlook error 0x800CCC0E is a poor internet connection. To check if your connection is stable, look for any configuration and hardware changes that are causing the loss in connectivity.

Check the settings for the email account on Outlook

Another reason for the error could be the settings in your Outlook email account. Some invalid changes in Incoming, Outgoing, Username, and Password settings could result in the error. Make sure that all the settings are appropriate. While troubleshooting the account settings, ensure that the username contains your whole email address in it.

Delete emails if they look suspicious

If you receive any malicious emails, delete them as they could potentially create issues like blocking of messages. To delete these messages from the mailbox, access it using the web-based program.

Clean all messages stuck in Outlook

To clean the messages that are stuck in the Outlook outbox, choose the “Work Offline” option found under the “Send/Receive” tab. Go to the “Outbox folder,” and then delete the messages or move them to the Draft folder.

Check the antivirus app and disable it

The antivirus program installed on your computer could be another reason behind the error code. You need to disable the antivirus that’s running as it could be preventing you from connecting to your email account. You should enable the program only after the error has been resolved.

Check your firewall configurations

Ensure that your firewall isn’t blocking Outlook from accessing the internet.

As you follow this suggestion, you should proceed with caution to avoid causing more problems as this method is associated with several security risks.

Delete “copy-cat/similar” accounts

If you have duplicate profiles, it’s highly likely that that’s the reason for the occurrence of the error. Delete the extra account and check if the issue gets resolved. To do this, go to “Settings” under file, go to the Email tab, then select the duplicate account and click “Remove.” Lastly, click “Yes” to confirm, and then restart the program to see if the problem has been resolved.

SMTP server settings

The error 0x800CCC0E can also happen due to the SMTP server settings and email configuration settings. This issue may either be resolved by changing the outgoing server settings or changing the server port number.

Once you have tried these two options, you should try restarting Outlook to see if the issue has been resolved.

Increasing the server timeout settings could also help resolve the error.

Verify your Outlook profile

To check if there are any issues with your Outlook account, create a new account, and then try sending or receiving messages on the new account. If that works, then make this new account your default profile.

Start Outlook in Safe Mode

Restarting Outlook in Safe Mode is highly likely to resolve the error.

If you’re using Windows 10/11/8/7/Vista, go to the search bar and type “outlook.exe/safe” and press “Enter.

If you’re using Windows 2003/2000/XP, go to Start > Run and type “outlook.exe/safe.” After that, click “OK.

While still in Safe Mode, you can try a few Outlook recovery tools.
