Is there a check or process inside of Outlook 2003 that will check to make
sure that there is not a duplicate of the email that is being moved into a
folder.

I have found by accident that several folders have duplicates, of course,
using up memory unnessecarily. Why would Microsoft allow such a waste to
begin with surprises me..

No I have to use another plug-in to find and delete duplicates.

Thanks
