When I try to send an email to a list of email addresses from an excel file Windows Live Mail (WML) only sends it to addresses that are in my contacts list.  The other addresses get a pop-up window labelled Name Check and reporting that that particular address has not been found.  How do I turn off this check?  It appears to be a problem in the Word-WML interface as WML itself has no problems sending to addresses not in my contacts list.
