Error 0x800CCC0F

When you start Outlook Express or try to send an e-mail message, you may get one of the following error messages:

Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Account: '', Server: '', Protocol: POP3, Port: 110, Secure(SSL): No, Error Number: 0x800CCC0F

This problem is often modem related. The first step is to:

  • Check your Outlook Express settings, making sure that the POP3 and SMTP servers are as listed in your account activation email, and that your full user name and password are correct. (Tip. Watch out for SMTP spelt as STMP, and that commas are not there in place of full points).

  • If this is OK, check your connection to the internet is ok.

  • If you're still having problems, it could be that Outlook Express is itself corrupt. Microsoft's instructions on how to delete it and reinstall it, along with making a backup of your address books etc.

  • Other suggestions by Microsoft are available here.

  • If this has still not resolved your problem Symantec Security Systems have detailed information on modifying your system settings available here.

  • If you have Norton Internet Security or Norton Personal Firewall and you will need to modify their configuration as advised by Norton.

  • Ensure you do not have email protection setup on your system.
