Similarly while encrypting the message, if the recipient’s digital certificate is not available the Outlook warns that the certificate is not available and if the user wants to send the message as an unencrypted message.

When the sender send a signed email, the sender’s private key is used to digitally sign the message. Depending on the private key security level the sender established when the sender first installed the sender’s personal digital certificate, when the sender click on the Send button, the sender may receive either an OK/Cancel prompt or a prompt for the sender’s private key password. If the sender selected a private key security level of "Low", the message will be sent without warnings or prompts.

The sender can send encrypted email to anyone who has a digital certificate. Simply ask the sender’s correspondent to send the sender a signed email or the certificate file as an attachment.
