Thread: Winmail.dat

Hiya,
has anyone has a problem when trying to send emails to certain people , instead of the coming up with the attachment ment it just replaces it with winmail.dat? I know what winmail.dat is but i dont know the solution for it. Im not using rich text formatting, im using HTML to send messages and it still doesnt work with some people :/
Any Suggestions?

Cheers,
