Well, I’ve been testing Lookout for quite some time now, and I must recognize that’s one of the best tool I’ve used. When like me you’re an archive junkie, you have a tendency to have huge pst files. And when I say huge, I really mean HUGE. With Lookout, I can search all my post archive whenever I blog about something. Invaluable. And it can also index your documents. This is an absolute must have.
