Both the duplicate removers from Sperry Software and MAPILab can process
multiple folders at once.

Additional duplicate removers can be found here but I haven't verified if
they can process multiple folders at once. Their description or trial
version should be able to shed more light on that.

We have a few different contact folders in our public folders we use
to track clients, and contacts, and a mailing list. I would like to
be able to quickly identify if people are duplicated in these
folders. I have found programs that will scan one folder for a
duplicate, but I would like to compare across multiple folders. Is
there a way to do this?

Thanks!
