When you need to protect the privacy of an email message, encrypt it. Encrypting an email message in Outlook means it’s converted from readable plain text into scrambled cipher text. Only the recipient who has the private key that matches the public key used to encrypt the message can decipher the message for reading.

Protection of your Outlook data is already managed by Microsoft Exchange. When you set a .pst password, it is set for the entire .pst file.
