You need to capture a copy of the message as it passes through
Postfix, use sender_bcc_maps with a suitably uncommon sender address
to avoid capturing unrelated traffic. Direct messages for the bcc
recipient to a dedicated mbox or maildir.

Once the message is received, post a copy here. We need to see the
MIME encoding of the iPhone's original message. Exchange re-encodes
MIME messages into MAPI in an irreversible way so not much useful
can be learned by looking at the Exchange mailbox alone.

If you can configure an IMAP client (say mutt) to talk to Exchange's
IMAP server, also post the rfc822 message source as seen by mutt
(e.g. save the message to an mbox file).
