Problem with s/MIME encryption Protocol.
Good afternoon. There is a PFX certificate that is registered in MS Outlook and thunderbird. When you try to send an encrypted s/MIME Protocol to an email from MS Outlook, the email arrives encrypted. But when I try to send an encrypted email using s / MIME with thunderbird to MS Outlook, the email is sent unencrypted. What could be the problem?
