Only save the property in MAPI and call MAPI SaveChanges
worked and did not leak plaintext but this caused outlook
still to break the attachments of PGP/MIME Mails into two
attachments and add them as winmail.dat so other clients
are broken.
Alternatively reverting the mail, saving the property and
then decrypt again also worked a bit but there were some
weird side effects and breakages. But this has the usual
problem of a revert that the mail is created by outlook and
e.g. multipart/signed signatures from most MUA's are broken.
Some things to try out might be the close approach and then
another open or a selection change. But for now we just warn.
