    2025-01-26 JOSEPH Works completely fine for me in Edge browser. I am using the last version: 20.20.514.1 (May 19, 2020). Have you set the S/MIME options? Check: Microsoft websites, Other work or school domains. Then add the domain to the list you trust: For example: webmail.apps.com

    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."?
