Every time you send an e-mail (compose, reply to or forward a message)
b)
Only when you ask for it by clicking on the sign button.

Encrypting e-mail messages with Outlook
The
process of encrypting messages so that only the recipient can decrypt them,
requires the use of the recipient's certificate (containing his or her public
key) in your address book. To get the recipient's certificate you can ask him to
send you a signed e-mail first (which will contain certificate and his or
her public key), or you can find the certificate online from Comtrust public
directory (please refer to LDAP procedure.
You
can encrypt your messages individually each time you want to send an encrypted
message, or you can configure security options so that your messages will be
automatically encrypted every time the recipients digital certificate is
available in your address book. This is done by following the instructions
similar to Digital Signature but with selecting the encryption options
instead of signing option.
