Always HTML, always sent by Outlook. If you view the message source via
IMAP with your favourite client you should see that...
The message is in fact intact and has all of the text in it.
The plain text part of the message is fine.
The HTML is blank in some clients as there is a badly written style
sheet, that has an <if !=mso> which I understand to mean if the client
is not Microsoft. Outlook can't display because of this HTML bug but
some other clients can.
I first came across this on the 17th Of Jan and surprise, surprise there

patch is the cause of it becoming visible but not the actual bug as if
it was there would be noise on the net about it. I've been trying

There is some suspicion (among my colleagues) of the phishing code.
This is all very vague so if anyone else has some good solid testing to
