How to fix Outlook Error Code 0x800ccc0f?

It is possible that the error message 0x800ccc0f can be solved by a few simple steps. Try this out first:

  • Option 1: Your antivirus is blocking the connection

Some types of antivirus have a mode of operation that is between the internet connection and the mail program and can intercept the messages that you send and receive with the mail program. The message exists to the antivirus, which is scanned and then transmitted to the mail server.

This way of working can make errors with large mail messages and have attachments, especially on slow equipment (little CPU, RAM or many programs running at the same time).

To check it, temporarily disable your antivirus and send the message again. If the operation was successful, the problem appears in the antivirus, which must be configured again so that it does not intercept your mail messages.

  • Option 2: Your firewall is blocking your mail client

If you have a firewall, you may not have open internet access for Msimn.exe (Outlook Express) or Outlook.exe (Microsoft Outlook) applications.

In the same way, your firewall may not have opened port 110 for receiving mail and port 25 or 587 for sending mail.

In this case, you can act in the same way as in the previous point: Temporarily disable your firewall and send the message again. If the operation was successful, the problem occurs in the firewall, which is blocking the ports used for sending and/or receiving messages. You must reconfigure your firewall by using ports 110, 25, or 587.

  • Option 3: The attachment is too large

If the error is unusual, it may be because Outlook is trying to download a message with a fairly large attached file by saturating your antivirus scanner.

  • Option 4: Saturated connection

There may be problems connecting to the internet or cuts in transmission as a result of saturation. If you share your connection with different equipment it may happen that they do not have enough broadband out (to the internet).

To verify it, make sure that only you use internet access. Then send the message again. If the problem persists, you should contact your ISP.
