I get this error when trying to download email: Server Response: '+OK 752 octets follow.', Port: 110, Secure(SSL): No, Error Number: 0x800CCC0F

It is a known problem with Outlook / Outlook Express that when a malformed message (i.e., an email with messed up header) exists in the user account,  Outlook / Outlook Express will error out when attempting to download the malformed message.  All email messages awaiting download that is dated after the malformed message will not be dowloaded.

We have confirmed with Microsoft Technical Support that this error is caused by a problem on the client computer, rather than an email server issue.  Microsoft suggested that this error is most likely caused by Antivirus Software.

Symptom 1
When attempting to download email with POP3, the email download will proceed and stop when reaching a specific email message and the following error will occur:

Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Account: 'Test', Server: 'mail.YourHostedDomainName.com', Protocol: POP3, Server Response: '+OK 752 octets follow.', Port: 110, Secure(SSL): No, Error Number: 0x800CCC0F

Symptom 2
The email message list within the webmail interface will show a message dated 12/31/1969

No known solution at this time.

Remove the malformed message (with message dated 12/31/1969) using the Webmail interface. Then download your email to your Email client.
