I found the property for the Message-ID and added it to the headers.
What you get is the same message-id that an external user would see if
your Exchange server sends the message on via SMTP.

I'll try to have a look at some of the others when I have more time,
unless you beat me to it. <wink>  I see a PR_IMPORTANCE property that
can probably be used for importance if we figure out what its integer
values translate to.  For date, there are two properties to choose
from, PR_CREATION_TIME and PR_CLIENT_SUBMIT_TIME. Both appear to be
UTC times, but that could just be the way dump_props is showing them.
For x-mailer, the only thing I see is what appears to be the Outlook
version number of the sender.
