Delete Duplicates for Microsoft Outlook v6.2.0.1

Delete Duplicates for Outlook enables you to delete duplicate e-mail
messages from your Outlook mailboxes. It is a add-in, i.e. an
auxiliary program that interfaces with Outlook, can operate in and on
the Outlook environment, and provides functions that Outlook itself
does not provide. Why the need for this program, since if you see
duplicates you could delete them yourself? The answer is that many
people now conduct much of their professional and personal
communication -- indeed much of their professional and personal lives
-- via e-mail, and some people use Outlook as their filing system for
correspondence. This leads to a situation in which people have
hundreds or thousands of Outlook mailboxes on their computer,
containing thousands or tens of thousands of messages, and this can
make it difficult or impossible to even spot duplicate messages,
especially if they reside in different mailboxes.
