Microsoft (actually MSN) recently purchased Lookout a search engine for Outlook. This comes as a bit of a surprise, but does incidate that people are using email differently today than a few years ago - and Microsoft is taking notice.
Similarly to the GMail philosophy, people are keeping old emails around for reference and not taking the time to organize them. With Lookout it doesn’t even matter how yoru email is organized - you can find just about anything in seconds. Literally.
This is incredibly more convenient than using folders, which can be a pain to keep up with. Even with Outlook’s rules wizard moving messages into folders automatically, organizing by folders presents a problem since some messages could be classified in several of your folders, etc. With Lookout you can keep your messages in a few folders - or even a single folder - and find whatever you need instantly.
If you want to search for messages from John, just type in from:John - add a few keywords if you like. If you want only messages that have attachments use attachments:yes - or search within the attachment file name itself using attachment:keyword. You can also restrict searches to date ranges, so it is easy to quickly find messages within the last week or two.
Lookout has totally changed the way that I use email - saving me countless hours every day. It appears that Microsoft realizes that searching is the next killer feature for email, especially as people receive and save more and more emails. With PC technology improving year after year, it is not unrealistic to think that many people will simply save all of their emails for all time. Why not? My current Outlook PST file, which goes back several years, is only 2GB - a pittance when compared to today’s hard drive sizes - not even the size of a single-layer DVD.
Good luck to the Lookout team (some of whom have joined Microsoft) on further development - let’s hope that Microsoft gets this one right. BTW, you can download the current version of Lookout here but it may not be there for long. At first it was removed, then placed on Microsoft’s website, then removed from there and placed back on Lookout’s site. So, get it while you can!
