Actually mail from an Exchange server - whether through an Outlook
or Outlook Web - does not have a Received header at all. The first one
you see will be added by the next server upstream.  Instead it will have
X-MimeOLE: Produced By Microsoft Exchange Vx.x

Exchange will only add a Received header when it relays a message
via SMTP.
