I have noticed that my Outlook 2003 Autoarchive is not deleting my old
email. I have checked my global Autoarchive setting and it is turned on.
 I have set folder specific Autoarchive settings. Most of these are to
operate on email older than 4 months, either sending it to the
Autoarchive .pst file, or deleting it. This is not happening; I have
email much older than a year.

I looked this up and read that the Autoarchive process for email goes by
the "received date or the last modification date/time, whichever is
later."  So I looked at both dates for all my email.  The problem is
that most of them have an empty modification date.

So, my question is: When autoarchiving email, does Outlook consider an
empty modification date to be later or earlier than the received date?
