This article provides a comprehensive troubleshooting guide to help you resolve Outlook error 0x800CCC0E and regain seamless access to your email account.

Understanding Outlook Error 0x800CCC0E

Outlook error 0x800CCC0E is often associated with the following message: “The connection to the server has failed. Socket Error: 10060, Error Number: 0x800CCC0E.” This error indicates a connection problem between your computer and the mail server. It can occur due to various reasons, such as incorrect server settings, network issues, firewall restrictions, or antivirus software conflicts.

Troubleshooting Steps to Fix Outlook Error 0x800CCC0E

1. Verify Server Settings

Start by double-checking your email account settings in Outlook. Open Outlook, go to “File” > “Account Settings” > “Account Settings.” Select your email account and click on “Change.” Ensure that the incoming and outgoing mail server settings are correct. Contact your email provider or IT department if you are unsure about the correct settings.

2. Check Network Connection

A stable internet connection is crucial for Outlook to connect to the mail server. Verify that your internet connection is active and working properly. Try opening a web browser and visiting a few websites to confirm connectivity. If you are using a Wi-Fi connection, consider switching to a wired connection for a more stable network.

3. Disable Firewall and Antivirus

Firewall or antivirus software may sometimes block Outlook’s connection to the mail server, resulting in error 0x800CCC0E. Temporarily disable your firewall and antivirus programs to see if the error persists. If disabling them resolves the issue, add Outlook as an exception in the security software settings or switch to a more compatible antivirus/firewall solution.

4. Check Port Settings

Incorrect port settings can lead to error 0x800CCC0E. For most email providers, the standard incoming and outgoing ports are 993 (IMAP) or 995 (POP3) and 465 (SMTP) respectively. However, certain providers may have different port numbers. Verify the correct port settings with your email provider and update them in Outlook’s account settings.

5. Reset TCP/IP

Resetting the TCP/IP (Transmission Control Protocol/Internet Protocol) stack can help resolve network connectivity issues. Open the Command Prompt as an administrator and enter the following commands one by one: “netsh winsock reset” and “netsh int ip reset.” Restart your computer after executing the commands and check if the error persists.

6. Repair Outlook Data Files

Corrupted Outlook data files can cause various errors, including 0x800CCC0E. Outlook provides a built-in repair tool called Scanpst.exe (Inbox Repair Tool). Close Outlook and search for Scanpst.exe on your computer. Run the tool, select the Outlook data file (.pst) associated with your email account, and initiate the repair process. After the repair is complete, open Outlook and check if the error is resolved.


Outlook error 0x800CCC0E can be frustrating, but by following the troubleshooting steps outlined in this article, you can resolve the issue and regain access to your email account.
