I have OL 2007 configured with a POP3 mail account. There is no email certificate installed on the client. I tried to send an encrypt email to a recipient who is in the OL contacts list with his certificate stored in there, but it was not successful. First of all, there was no encrypt email icon in the ribben. If I checked the Encrypt message contents and attachments check box under Message options\security settings and hit the send button, a Invalid Certificate error message pop up and said Microsoft Office Outlook cannot sign or encrypt this message because you have no certificates which can be used to send from the email address (my pop3 email). What I need here is to send some encrypted email using his/her public key, I don't need to sign any email so I presume I don't need to install my own certificate. Any idea?
Thanks
