What will happen to my old encrypted emails when I receive a new S/MIME certificate?

It is important that you retain the expired S/MIME certificate with the corresponding private key. Thus, all e-mails encrypted with this S/MIME certificate and the corresponding private key remain readable for you.

If the expired S/MIME certificate or the corresponding private key is deleted, you can no longer read all e-mails encrypted with this certificate in plain text.
