Indeed in Outlook you can (dis)(en)able an option (in the voting and
tracking options) like the receipt acknowledgement to receive an
acknowledgement when the message has been read.
I'm not sure of the cause of this, but there is one strange header tag
that persists in all of them:
X-MS-TNEF-Correlator: 00000000EBB9C52FD2A7BD11B1AD0E4FB77C60A304E72100
Does this ring a bell with any of you Micro$oft gurus? They seem to be
some variant of a receipt acknowledgement.
