Hi Rafik, sorry I cannot help because I am a Linux user but I am sure that someone who is a Microsoft user on the site will help. But welcome to PC Review it is always good to have a new member and please participate.
Which version of Outlook are you using? I'm not sure what you mean by auto-BCC for all incomming emails - do you mean outgoing or have I misunderstood? If you could explain a little more I will do my best to help.
