I generated the key and installed the certificate for a Digital ID for Secure Email, and then tried to send an encrypted email to a contact at another company. They were unable to read the encrypted email, and when I sent it, I got a message that said "Microsoft outlook had problems encrypting this message because the following recipients had missing or invalid certificates, or conflicting or unsupported encryption capabilities: emailofperson"
What do I have to do to make sure the person I am sharing encrypted email with can read my emails? I've never used encryption before and don't know much about how it works.
Thanks
