(Outlook 2002, SP3)

I have an Outlook custom form, public folder based, and it has been working
mostly. When it works a new form instance would be stored in a public
folder. However a user has aproblem where after filling out a new form and
clinhg the send button, teh form is sent as an attachment (with .msg
extension). I ahve got the attachment (and coudl save it as an .oft file if
desired). How can I save/convert the .msg attachment (or .oft file) as a
proper form instance in teh public folder?

Thanks
Long
