PGP encrypted messages arrive blank with no content when sent to Microsoft Outlook 2003 mail client.
There are no errors displayed, emails are delivered, but they are blank.
To encrypt or decrypt email, PGP Desktop uses a messaging proxy which monitors email to encrypt or decrypt messages when needed. PGP Desktop monitors the email traffic between your email client and your mail server. Depending on the circumstances, PGP Desktop will intercede to encrypt, sign, decrypt, or verify messages. If the messaging proxy is not working or configured correctly, the decryption of the message fails.
