If a mixed setup in Outlook with S/MIME Crypto from Outlook and OpenPGP Crypto from GpgOL is used, there is a corner case we should fix:
How to reproduce: Set up new mails to be always signed via Outlook's own S/MIME crypto. Additionally choose GpgOLs "Secure" button in the message menu. Then you will get the following warning on "Send":
If you choose "Yes" and the security dialog comes up (maybe you do not have an OpenPGP key for the recipient) and you then abort sending here, the original crypto settings are not reset. If you now deselect "Secure" and send again, the mail will be send without S/MIME signature by Outlook (if you did not reset it manually in the options menu). This might be unexpected if you are used to Outlook signing by default.
Therefore we should restore the original Outlook crypto settings of a mail if sending is aborted.
