You may get one or more of these errors when you try and send or receive emails, and occur because Outlook or Outlook Express cannot communicate with the email server. They are usually caused by:
- Incorrect account settings
- Misconfiguration of personal firewall software
- Antivirus software
- A bad modem
- Maximum Transmission Unit (MTU) size
- Outlook Express has been removed from the computer or the installation is damaged
- Your user profile in Outlook is damaged
- An e-mail item on your POP3 server is damaged
