How can I add a password so when I start Outlook 2007 No one can see my inbox

how can I add a password so when I start up Outlook 2007 No one can see my in box.
Only when I enter the password I can see it?

Most users just password protect their Windows logon Username (ie not Outlook)
I think it would be much easier to do this by having your own Windows passworded account

adding a password to the account also adds a bit of security to the system

But remember if you haven't entered anything into The current box password leave it empty :D and type in the new pass and verify
