I can only get that message when I right click on an item and choose> send to> mail recipient.
I don't get it if I attach it while in live mail.
It appears to be related to sendmail.dll which cannot be disabled.
Which explains why you haven't seen any answers for all the other people asking that.
If you don't want that message I guess you're stuck with opening live mail and attaching from there.
