Error 0x800CCC0E is a common Microsoft Outlook error that typically occurs when there is a problem with the Simple Mail Transfer Protocol (SMTP) server settings. To fix this error, you can follow the steps below:

Verify your internet connection: Ensure that you have a stable internet connection before proceeding. Unstable connections can cause issues with sending or receiving emails.
Check SMTP server settings: Open Microsoft Outlook and navigate to "File" and then "Account Settings." Select the email account experiencing the error and click on "Change." Verify that the SMTP server settings (including the port number) match the settings provided by your email service provider. Common SMTP server settings include "smtp.yourprovider.com" for the outgoing server and port numbers such as 25 or 587.
Disable antivirus and firewall temporarily: Temporarily disable any antivirus or firewall software you have installed. Sometimes, these security programs can interfere with email communications. Check if the
error persists after disabling them. If it resolves the issue, reconfigure your security software to allow Outlook access.
Correct SSL settings: If you are using Secure Sockets Layer (SSL) for your email account, ensure that the SSL settings are configured correctly. Set the correct port number for the SSL-enabled server (e.g., port 465) and enable SSL encryption.
Test alternate SMTP ports: Some internet service providers (ISPs) block default SMTP ports. Try changing the port number to an alternative, such as 587, and check if the error is resolved.
Verify email account credentials: Double-check your email account credentials, including the username and password, to ensure they are correct. Incorrect login information can cause the error.
By following these steps, you should be able to fix the Microsoft Outlook error 0x800CCC0E and restore normal email functionality. Remember to keep your Outlook and operating system updated to ensure you have the latest bug fixes and security patches.
