Need Help With Attachment

[Julia26907034r74s]

I downloaded documents and saved on my computer. I can see the attachments just fine.  When I am asending it to someone, the preview and what they receive looks like the attached picture. How do I get rid of this message when I send an attachement to a receipient?

You can't, unless you convert the file from being an XFA form to a regular PDF.
