Error Number: 0x800CCC0E

When using Microsoft Outlook, the message Error Number: 0x800CCC0E may appear. There are several possible reasons. These are outlined below along with the possible solutions and workarounds.

Conflict with SMTP

The most common reason is a conflict between Outlook and the SMTP (Simple Mail Transfer Protocol). You’ll know it is the cause when the error message is accompanied by others. The additional messages may vary. The most common is the one saying the server connection failed. There will also be messages about socket errors and ports.

The reason it happens is this: when you log on to MSN, Outlook doesn’t permit the relaying of messages to SMTP. For this reason, the message appears.

Solution for SMTP Problem

  1. The solution for the Error Number: 0x800CCC0E is usually quite simple. Just setting the SMTP server to be the same as the one used by MSN will fix the problem. To do this, go to the Tools menu. Click Accounts. Select Mail and choose your account (and any others you need to alter). Click Properties.
  2. Go to the Server tab. In the information section erase the text in the Outgoing SMTP Mail. Type in
  3. Next go to the Outlook Mail Server options. Choose My Server Requires authentication. Click Settings. Go to the Login Information and click Log On Using. In the Account Name put in your MSDN ID. Do not include the text after the @ sign of your ID.
  4. For this Error Number: 0x800CCC0E solution to work, enter your password in the appropriate box. Put a check on the Log On Using Secure Password Administration. Click OK and close all the windows until you return to the main Outlook screen.

The IE Repair Tool

Internet Explorer 5 and up have a repair tool built in. You can also try this option. Go to Add/Remove and choose Internet Explorer. Choose Repair from the options that appear. After the repair, you’ll need to restart the computer.

Other Solutions

  1. If the problem persists, you can try changing the port in Outlook Express. Head over to Tools and select Options. Choose Properties and then Advanced. Set the incoming to 110. Type in 25 for the outgoing port. Finally, remove the check for the This Server Requires Secure Connection. Restart Outlook and see if this removes the Error Number: 0x800CCC0E message.
  2. If it doesn’t work, go to Accounts. Delete the one you’re using and make a new one. Enter the appropriate data. You need to have all your network settings with you just to be sure the info you put in is correct. If that doesn’t work, turn off any firewall installed. You can also try entering in the mail (incoming) option.
  3. It’s also possible that your antivirus program is interfering with it. Try turning it off. If that works, reconfigure your antivirus so it doesn’t cause a conflict. If that’s not possible, get another one.
  4. There’s no need to be unduly alarmed when the Error Number: 0x800CCC0E appears. It’s usually just about a conflict of servers. Using any of these methods, the problem will be resolved.
