When you attempt to send and receive e-mail you get one of the following error messages;

The operation timed out waiting for a response from the receiving (POP) server 0x8004210a

A time-out occurred while communicating with the server 0x800ccc19


This error message may occur if Microsoft Outlook or Microsoft Outlook Express cannot establish a connection with your e-mail server. These error messages are frequently caused by one of the following:

  • You are not connected to the Internet or a network, or your mail server is temporarily unavailable.
  • The mail server domain name is not correct, has not been registered, or has not had sufficent time to propergate throughout the Internet
  • Your account settings are incorrect.
  • Your user profile in Outlook is damaged.
  • An e-mail item on your POP3 server is damaged.
  • The configuration of your AV software is incorrect.
  • Outlook Express was removed from the computer or the installation is damaged.
  • The configuration of your personal firewall software is incorrect.

If you’re sending an e-mail with a large attachment, you may also see this error. This is because the file size of the attachment in the e-mail message is too large, the e-mail message cannot be sent within the time limit. As a result, the message is sent repeatedly.
