Password on Inbox

I'm using Outlook 2003 on my company network, and I want to set a
password on my Outlook Inbox, so that anyone who accesses Outlook on
my laptop, will not be able to view e-mails without the password.

I need to give someone a loan of the laptop, to do some checks whilst
I am out of the country, and I don't want them snooping arouond my e-
mail. I've already got a password on my personal folders, and just
wondered if one could be set on my Inbox as well.

TIA
