P-EncryptMail for Outlook allows you to encrypt your Outlook email messages using strong encryption algorithms (AES, Blowfish, Twofish, TripleDES). You can encrypt an entire mail folder or only selected messages, including attachments. All you have to do to encrypt/decrypt a message is click a button on the newly added toolbar. You can also use the software to send encrypted messages, however the receiver needs to install a free software in order to decrypt the message.
