Scanned attachments nested inside email attachment

[rjmattern]

Our copiers scan and email attachments to the user's inbox.  In the past, the email would arrive with the scanned pdf attached.  Recently, the email arrives with another email attached with the scanned document attached inside that attached email.  I'm not sure why we are getting the nested email attachment all of a sudden and how to fix it.

DO you have the ATP Safe attachments functionality enabled?

No, I do not think we do.  I went to Security & Compliance>Policy and did not see a safe attachments tile.
