What happens to encrypted mails when CA certificate expires in my Windows Domain
- by Wolfgang
does anybody know what will happen to encrypted /signed mails when a root authority certificate expires in my domain network? Can the certificate still be validated from the clients and will the clients recognize that the certificate was valid when the mail was encrypted / signed?
Respectively what will happen when a migration to a new infrastructure will take place or if I install a new root-CA? Is there a need to also migrate the expired root certificate?
