"Not Implemented" error with Microsoft Office Outlook

[vratz]

I'm not able to do any operation with my outlook, i could only just read the
mails expect that nothing can be processed. When im trying to perform any
action it is giving an pop-up error message "Not Implemented". Can somebody
give the solution for this. I tried lots of solutions but did not work out.
My system has windows XP OS.

Thanks
