Signing inline with Outlook 2016

Dear Comodo Community,

I use Comodo Internet Security and have a Comodo security certificate.

What I would like to do is to sign emails inline so that there isn’t the s/mine p7s attachment.

My problem is that I quite often use the has:attachement or similar feature to find specific emails. If each email I send has a smime.p7s attachment it makes it impossible to search through my sent items. Is there a way for to sign the email inline in Office 2016?
