Back in July, Microsoft purchased a company
who made a tool that allowed users of Outlook 2000+ to search through their email at greater speed and accuracy to the standard Outlook search tool. Since Microsoft acquired Lookout, the MSN team have been steadily working on Desktop Search and web search technologies. Google announced their own Desktop Search technology recently; the tool is fast but is limited in capabilities.The MSN Toolbar Suite
integrates directly throughout the OS and varies according to where you're searching from. For example, if you're searching from within Windows Explorer you will search on your PC, in IE on the web and in Outlook the toolbar searches within Outlook. The bottom line : like the new online search, Microsoft have made a very good effort to get back in the game.
