S/MIME in Outlook for Android not recognized RRS feed

  • Question

  • Hi,

    I've got a valid S/MIME certificate issued by GlobalSign on my Android MI A3 (Android One) installed for VPN and apps.

    The certificate contains the proper KUs and EKUs and my email address in the SAN.

    The most recent version of Outlook for Android supports S/MIME under settings -> Security.

    You can only slide it on or off.

    After restarting the app the option of digitally sign and encrypt becomes available.

    However Outlook for Android keeps stating:  We couldn't find your S/MIME certificate. Install a certificate or please contact your IT help desk.

    As I am the IT help desk, I'm asking my question here, I'm hoping someone can help.

    Where does Outlook for Android expect the S/MIME certificate and key to be installed other than in the default Android certificate store?

    Does anyone know why Outlook for Android cannot find the S/MIME certificate?

    (I know about the iOS requirement of using Intune but this doesnt seem to apply to Android)

    I saw the threat https://social.technet.microsoft.com/Forums/de-DE/29c8b97b-3b87-4880-bf72-94c864c9737e/solved-outlook-for-android-smime-certificate-not-found-?forum=outlook (and stole the text) but reuploading the SST did not help.

    Any suggestions?
