Outlook 2003 – Blind Copy

Hello all,

My boss wants me to find a way to set up Outlook 2003 on each client PC to automatically blind copy him on everything that is sent. I have found plug in apps on the internet, but he wants me to set it up so that the employees do not know it is happening, and so that they cannot disable it. Any app I have found installs menu options and stuff that would be noticed by people, and they would be able to disable it. I am wondering if there is a registry hack or something. Thank you in advance.
