[POST UPDATED - SEE COMMENTS FOR THE LATEST!] Those with ageing memories have long enjoyed the powerful search capabilities in Outlook using add-ons like Lookout or Windows Desktop Search. I'm loving the latest beta of Outlook 2007 (I'm running the Beta 2 Technical Refresh) and the search seems quicker than ever. In fact I'd describe it as "Instant". Which is handy because the all-important keyboard shortcut you need to remember is ALT+i to activate the instant search in your current Outlook view. Trust me, you'll be using ALT+i a lot so commit it to memory before you forget!
