I don't know about outlook specifically, but basically every mail 
program on earth understands MBOX format.

mailutil from uw-imap would be an excellent choice. While it could use 
some documentation, it works a treat for many tasks involving mass mail 
maniuplation. I've been using it to migrate users from our awful MDaemon 
3 (WinNT) server to the Cyrus server, but it can also copy from IMAP 
servers to local mbox files.

something like this might work:

mailutil transfer {$HOST/user=$USER/notls/norsh}INBOX $TARGETDIRECTORY

but I haven't done this specific task with mailutil so YYMV.
