Sign e-mails in Outlook 2016

When I sign a mail in GPGOL in Outlook 2016, it doesnt sign the mail, all it does is add a encrypted copy of the mail in the bottom
(BEGIN PGP MESSAGE…), it does not add the expected
"BEGIN PGP SIGNED MESSAGE …BEGIN PGP SIGNATURE…
This means that i can edit the mail after, and when I do the verification it pops up green, with the original message (and if I think I just verified a signature, i might not optically compare the decrypted message with the received message, and just close the window…)

Bug? Or have I missed something?

Hi Rickard,
which version of Gpg4win are you using?

Hello.

I had the exact same problem, and it is resolved in the upcoming 3.0 release. Try it out by downloading beta from this page.
