Event log for public folder outlook 2000

i want know whether a particular user who might accidently deleted a file(who were given the permisssion as editor) in public folder outlook 2000. Or some might even intentionally/unintentionally posted some confidential files to outsider and etc....
is it possible at all to identify at all?? What i want is actually an "event log" for our public folders - a record of who has done what at what time, just like the "event log" feature in windows NT.
how to approach this??
