How to fix the POP error 0x800CCC0F when receiving mail with Outlook 2002 and 2003

The whole error message looks like this:

Task '' reported error (0x800CCC0F) : 'The connection to the server was interrupted. If this problem continues, contact your server administrator or Internet service provider (ISP).'

The first thing to do, as with any other error, is to check the settings for the account in the email application. One cause to receive this error code is a wrong port number. Particularly, if you have enabled SSL encryption for the POP incoming server but you have set the port number to 110. The correct port number for an encrypted POP connection is 995.

The same issue (wrong port number) in Outlook 2007 will produce a different error code ( 0x800CCC1A). In Outlook 2010 you'll get a message that your server does not support the connection encryption type you have specified.

Another thing that is known to cause a wide range of error codes is antivirus software/firewalls. In particular, Symantec products such as Norton Antivirus or Norton Internet Security can cause this error. Disable your antivirus application and firewall and test your email account again. In the case with Norton you might even have to uninstall the application to be completely sure that it's not the problem.
