No, it doesn't. The messages stored in it will always be larger. FWIW, it
defeats the purpose of exchange if you use a pst - you can't use owa or
share calendars etc.

Hi Diane,

Thanks for the reply. This is just to clarify one more issue. I have
got exchange mailbox on my XP machine. This by default is .ost file.
However I wanted the configuration in the old way of
mailbox-pst-smtp-stuff. Hence I created a 2003 outlook pst and set it
as the default PST where all the mails will get delivered; instead of
the .ost file which is created by default in the user profile.

So my query - is it even in this case that the mails delivered to the
pst file (default store) on my machine will always be stored in
smallest format? In other words, does outlook treat this pst (since it
is default) in the same way as if it were the .ost file itself.

Thanks again for your help.

Regards,
Mandar

oh, you didn't mention you were archiving your exchange mailbox. That
does
not use a pst (so there is not a 121 meg pst to compare it with) and yes,
the messages are much larger because of how Exchange stores messages and
attachments. An exchange mailbox store is always the smallest format.
