One more question...
The functionality about the reading pane is OK, but when a recipient hits
Reply or Reply All, the form and its data is again not visible, but is when
the recipient hits Forward...
Is it a similar functionality / limitation as to how attachments work in
Reply / Reply All as compared to Forward.

I have developed and published a Custom message type Outlook Form, there is
no issue with the form data retention, but when the Outlook form is sent and
reaches the inbox of the recipient, in the Reading Pane (Preview) of Outlook,
the form elements are not visible (i.e. looks blank) and when double clicked
the form and its data appears in a new window.

Is there a parameter setting that I am missing here to make the form and
data elements visible in the Reading Pane (Preview) area of Outlook.
