ACCESS 2007 AND HOTMAIL PROBLEM

have a Hotmail email account which I use with MSN EXPLORER as my mail
handler. I have an application written with Access 2007. I have downloaded
the software for viewing and using .snp formatted files from MSN website.
I created several reports in Access 2007 and want to email them to several
people in .snp format. My Browser, or Email Server I cannot tell which or
why "Blocks" .snp formatted files. I cannot find a swithch or Microsoft
doesn't seem to know why their software considers their software "UNSAFE".
Does anyone know how to make this work. It works if you are not using
Hotmail or MSN Webmail. it works with Earthlink to many various email
servers by Not Microsoft's go figure.
