2024-12-06 Hannjo Funktioniert nicht. Empfinde ich als Täuschung seitens Microsoft
2024-11-24 Heinz Ist nicht mehr zu gebrauchen im neuen und alten Outlook
2024-11-22 Paul Doet helemaal niets!
2024-11-20 Claes Jag håller med, får detta meddelande i Outlook. "Den digitala signaturen för det här meddelandet kan inte verifieras. Meddelandet har en digital signatur, men det verifierades inte eftersom S/MIME-tillägget inte är installerat" Och en länk till denna sida via knappen "Installera S/MIME-tillägg". Där det rapporteras att ""Tillägget är redan installerat i webbläsaren". Outlook borde rapportera att "...S/MIME-tillägget inte är konfigurerat."?
2024-11-18 Otakar Before installation there was warning "Digital signature on this message can't be verified...." but content of the message was readable. After installation content of the message is not visible because of never ending loading.
2024-11-11 Karanvir Extension is useless on Outlook.office.com (Edge/Chromium). After installing this extension, it keeps showing the loading animation without showing the email, or it keeps telling you to install "S/MIME" extension even when it is installed. Before installing this extension, it at least loading the emails, with a popup "This Message has a digital signature, but it wasn't verified because the S/MIME control isn't currently supported for your browser or platform."
2024-11-01 Wellington Unfortunately, it simply doesn't work. The messages keep appearing and I even stopped seeing some content. Don't install it, it's useless.

2024-10-21 Frank funktioniert nicht. Oder ist mieserabel beschrieben, wie es funktionieren soll. Oder beides.
2024-10-09 David Recebi um email da CGD que dizia não ter o certificado instalado, e como tal não poderia reconhecer a assinatura digital. Após instalar a extensão S/MIME, deixou de abrir o email sequer.
