Operation Failed. An object could not be found
 

I configured Outlook 2003 to work with comcast email. The tests all were
positive and comcast received the test email. When I select the send/recieve
button I get the message: "The operation failed. An object could not be
found."

Have not been able to locate explanation for error message. Any references
or ideas? I see others have this same problem. I would like to use this
progam for my email.
Thanks.
