I am unable to send an encrypted email to someone for whom I have a valid certificate, but they recently moved to a new company. Outlook is refusing to encrypt the email because the email address inside the certificate does not match the address I want to send to. Outlook is also refusing to even add the person as a contact with the mismatched cert.
How can I override this behavior?
Platform is Outlook 2013 running on Windows 8.
One possibility I suppose would be to compose the encrypted email using some tool outside of Outlook, then mail the encrypted content via Outlook after the other tool has encrypted it.
