Outlook 2016 is refusing to let me digitally sign an email, saying:
"Microsoft Outlook cannot sign or encrypt this message because you have no certificates which can be used to send from your email address.
Yet, I have two such certificates, each of which contain SubjectAltName containing:
"RFC822 Name=libove@felines.org"
(libove@felines.org is the email address from which I'm trying to send the message, as which I'm trying to sign the message).
Enhanced Key usage for these certificates include:
Secure Email (1.3.6.1.5.5.7.3.4)
Client Authentication (1.3.6.1.5.5.7.3.2)
So, why, really, is Outlook refusing to allow me to use these certificates to sign emails?
thank you,
