However Outlook for android keeps stating: We couldn't find your S/MIME certificate. The most recent version of Outlook for Android supports S/MIME under settings -> Security.Īfter restarting the Outlook app the option of digitally sign and encrypt becomes available. I've validated that the certificate and corresponding private key are properly installed manually, so they are not affected by sandboxing. I also have installed the intermediates for trust purposes. The certificate contains the proper KUs and EKUs and my email address in the SAN I've got a valid S/MIME certificate issued by GlobalSign on my Android Galaxy A40 (Android 9) installed for VPN and apps.
