I have Outlook 2007 and when I type in instant search (Search All Mail Items) it only comes up with a few (dates are no later than a few days) emails. Even if I type something as common as a sender like Trevor who i have hundreds of emails from, it will only show 3 or 4 emails. So if I type a specific word from an email that I know has that word from last month...it will not find that email. How do I rectify this so it truely searches all my mail, folders, and comes up with a full search?
