I got this from my ORACLE-L listserver. I don't use Exchange, but this may
be of help.

>
>Step #1:
>Double-click on the Mail and Fax icon in Control Panel.
>Click on the Services tab, and select Internet Mail from the list. If
>Internet Mail is not listed, click Add to add this service.
>Click Properties, and then Message Format.
>Turn off the option that reads Use MIME when sending messages.
>Click OK and then OK again.
>
>Step #2:
>Double-click on the name of the recipient in your Address Book.
>Turn off the option that reads Always send to this recipient in Microsoft
>rich-text format.
>This option needs to be set for each recipient of a message - if even one
>has this turned on, all recipients will still get the attachment.
