They won't have headers if they don't have PR_TRANSPORT_MESSAGE_HEADERS.

Only emails sent over the Internet have that property. If the email was sent
internally using Exchange the property and mail headers won't exist on that
item.

PR_TRANSPORT_MESSAGE_HEADERS contains mail header. For those mails which
dont have PR_TRANSPORT_MESSAGE_HEADERS property how to get their headers?
