Multiple copies of same message in archive

[reader]

Have Outlook 2003. At times when I import the archived file I find that
there are multiple copies of the same message. I have to (1) delete the
archive file, (2) painstakenly eliminate the duplicate messages, and then (3)
create a "fresh" archive file. Is there some setting that can be used to
prevent multiple copies of the same message in the archive file (pst)? Thank
you.

Why are you importing the Archive & not simply opening it?

I did not know that was the preferred method. Sorry. I am new to this
archive stuff. Thank you for your response.
