GooD Day, I tried to add exchange instant messenger to our exchange server and now the exchange system manager doesn't recognize the c:\winnt\system32\mapi32.dll file as the latest version. I tried re-installing SP3 and i added this mapi32.dll file in: http://oit.wvu.edu/tss/groupwise/howto/mapi32.html (though i haven't had a chance to reboot since i added this version in) and i still have the same error occur when i op[en exchange system manager. Does anyone have the latest mapi32.dll file or no how to obtain it? Many Thanks, Robert
