Not so important, yet surprising - S/MIME attachment there or not there

Typical webmail clients treat S/MIME-encrypted messages as an attachment, usually keeping its name "smime.p7m". OWA acts similarly when the attachment was sent with a client other than OWA. If the message was sent with OWA, the attachment is missing.

An interesting thing is that when the user activates the follow-up flag the attachment appears.

This phenomenon does not occur when the message is triple-wrapped.
