Unable to select encryption certificate

Question

I have a problem sending encrypted mails with Outlook 2016.

In order to encrypt mail I have to select encryption certificate for my account in Accounts -> Advanced -> Security dialog.

Encryption for digital signature can be selected, but drop down list for encryption certificate is empty.

This leads to error message when I want to send encrypted mail saying that no encryption certificate for this account is selected. When I send mail anyway it can not be decrypted in Sent Items folder.

However, mail is sent encrypted and recipient is able to decrypt it.

The same functionality works correctly in my other mail clients (Mail and Thunderbird).

Certificate from my PKI card is visible in KeyChain Access.

The only problem is that Outlook does not "see" it as encryption certificate.

Please help.
