After resolving a problem with my laptop not reading certificates stored on my Personal Identity (PIV) card. I've been able to decrypt email messages from others with Outlook 2016 on my MacBook Pro laptop running OS X El Capitan (10.11.6) by using my PIV card in the SCR331 card reader, but when I attempt to send an encrypted email, I see a message stating (image):
If I click on Continue the email will be sent encrypted so that it is readable by the recipients when their email clients decrypt it using their private keys, but I am unable to read the message I sent when it is placed in my Sent folder. To resolve the problem, I clicked on Tools on the Outlook menu bar, then selected Accounts, then clicked on the Advanced button. I then clicked on the Security tab and selected a certificate in the Encryption section. It had been set to "None Selected".
