S/MIME Reversion broken after disabling S/MIME Support
Closed, ResolvedPublic


When S/MIME support was enabled in GpgOL and is later disabled mails are not correctly reverted.

GpgOL should read a mail it read in the past but after reading change the message class back to the original class so that it's handled by outlook again.

Jochen can you please confirm that this works reliable for you too?

Send / Recieve some S/MIME Mails, read them with GpgOL. Then Disable S/MIME, read them again with GpgOL. Restart Outlook. -> Mails that you read with S/MIME disabled GpgOL should now be handled by Outlook again.

Versions Used: Gpg4win-3.0.0-beta17 with GpgOL-2.0.2-beta8 on Windows 10 (64bit) with Outlook 2016.


  • Open Outlook
  • enable S/MIME in GpgOL
  • Read S/MIME encrypted mail in Outlook
  • disable S/MIME in GpgOL
  • Read S/MIME encrypted mail again
  • restart Outlook
  • Try to read S/MIME encrypted mail

Result: Opening the Mail in the Inbox with S/MIME enabled GpgOL works fine. The ribbon ontop of the mail is displayed correctly. After disabling the S/MIME function the Mail is still displayed as it was with S/MIME enabled, nothing changed from the frontend side. As I restarted Outlook the mail can't be displayed anymore, because I have S/MIME not configured natively in Outlook.

I resolve this. If it is not displayed anymore it means that outlook should handle it.
