    Possible causes for this include server problems, network problems, or a long period of inactivity. I assume that you’ve ruled these out.

    The problem may also occur if you have an antivirus e-mail protection utility enabled, which checks the mail as it comes in from your Post Office Protocol (POP) server. To test this, disable the antivirus e-mail protection utility as well as the Windows Firewall.

    Another likely cause is that there is a message that is either too large or corrupt in some manner. Logon to your servers Webmail site and delete the offending message there.
