I don't know Outlook. I hope someone who does answers. Or you may want to
use an Outlook newsgroup:
news://msnews.microsoft.com/microsoft.public.outlook
news://msnews.microsoft.com/microsoft.public.outlook.General
Its not always your setup, but the person who is sending them to you. If the
sender sends them as attachments or if he INSERTS them into the email is the
way you will recieve them also.
