Microsoft offers a free utility called Lookout that you can download from Microsoft. It allows you to search for e-mails, contacts, notes, tasks, calendar, as well as data from Exchange, POP, IMAP, PST files, public folders, and even files on your computer or other computers. The tool runs on Windows 2000/XP/2003 and requires .NET Framework 1.1 and one of the following Outlook versions: Outlook 2000, Outlook 2002, or Outlook 2003.
You won’t find detailed instructions on how to install and use this tool as this is an “unsupported” tool from Microsoft. However, the tool is easy to install and use. The program adds its own toolbar, called Lookout. After you install the software, you may have to restart Outlook. You will see a Welcome screen shown below. Use the Search option on the new Lookout toolbar to locate information. The latest version available at the time of writing was Lookout v1.2.
