I hope this is the most appropriate place for this question.
According to

[http://msdn.microsoft.com/en-us/library/office/aa338201(v=office.12).aspx],
Outlook 2007 is meant to support body margin fully.
("body" › "Cascading Style Sheet Style Support Level" = "FULL".
"FULL" = "All of CORE and COREEXTENDED".
"COREEXTENDED" › "margin" + individual margin properties.)
However, this doesn't seem to be accurate, as you can't easily get rid
of the body margin. So, is there a secret way (mso- prefixed CSS
properties, @page rule, etc.) to set the body margin of an HTML email
to 0, in emails sent to (not necessarily from) the more recent Outlook
versions that use Word for rendering?
I'd especially appreciate if someone who works on the Outlook/Word
rendering team can share any insights on how to accomplish this.
