My version of Outlook (2007) does not print a date stamp. Perhaps someone set
a footer on your memo or custom style. To check, click Office button, hover
on Print, click on a style under Page Setup.
I don't remember how to do this in older versions; perhaps someone else can
help
Version of Outlook? Message format? If Outlook 2003 or older and HTML it
uses the IE print engine and I think the date you are referring to can't be
removed.
