I used to see Word and PDF attachements with my GMail account in Mail. Recently I added my new Outlook account to Mail and found that attachments are missing. So I asked my friends to send attachments to my GMail account and they are also not showing up. All I see in attachment is a winmail.dat file (no matter my friend sends a Word or PDF file over). This happens only after I upgraded to Mountain Lion. Just wonder if there's some setting I need to tweak, hopefully this is not a 10.8 problem. Thanks for any help.
