Outlook error message "The Operation Failed"

When I click Send & Receive in Outlook, I receive the error message "The Operation Failed." There is no message "An object could not be found."

I had not added or deleted a new profile or e-mail account.

Thank you for any assistance.

 

maybe your mail server is down? when the error happens, can you look at the error message in more detail ?

 

I think that your problem may have something to do with your firewall especially if it is Norton or Zone Alarm.

 

Knowing the problem was not the mail server and having no success at the MSN site, I did go to Symantc...I did an uninstall of NIS, a clean boot and the reinstalled NIS.
The problem had been with the intergrator.
Knock on wood, but i am again accessing e-mail from outlook!
Thank you for the direction.
