Microsoft Outlook 2007 Send Receive Not Implemented

I’ve been frustrated lately, since my Microsoft Outlook 2007 was not function properly. It gives me a strange (according to me) error message when I click the Send/Receive button. It said: “Not Implemented”. Just like that. How can I search for help, if the error message was only two words? But I’m hoping that here I can find somebody to give me some solution or any recommendation. Thank you guys…

Error:
Not Implemented
