Exchange cached mode and security

Can someone please show me how to password protect when opening Outlook in Exchange cached mode?
It looks like anyone can open the Outlook program and read messages even if I had selected the
"always prompt for username and password" option. This option is only good for protection against
reading new mail from the server only. I would like to protect existing emails by asking the user with a
username and password. Please help. Thanks.

The machine authentication is supposed to protect Outlook in that regard. What is to stop someone from opening a Word document on that machine? Or a notepad document.

The basic rule of security is that if someone has physical access to a machine, then you have no security. Unless you are using encryption and some other tools, given a standard Windows box, I can get access in less than 20 minutes.

Hi Sembee,
Thank you for your response. What you says makes absolute sense
and I've explain this to my boss for the 3rd time. Is there any link that you are aware
of that I could show my boss to convince further? I know its gonna be a pain but
we are under strict SOX guidelines and it happens to be a laptop.

I am not aware of anything written down as it is one of those that is just "presumed" that everyone accepts.
You would have to ask Microsoft whether they have anything that indicates how Outlook and/or Windows complies with SOX. It isn't anything I have ever needed to worry about as I am in the UK.
