Lookout indexes all Microsoft Outlook contents and provides a toolbar to search all emails, news feeds, appointments and attachments. It basically can index all contents of Microsoft Outlook to power the search. Advanced users will like the option to exclude folders from being indexed.

The Microsoft Outlook search add-in Lookout integrates itself nicely into Microsoft Outlook 2003 but needs a small tweak before it will work in Outlook 2007.

cd %SYSTEMROOT%\assembly\GAC
rename Microsoft.Office.Interop.Outlook Microsoft.Office.Interop.Outlook.OLD

To reverse the changes one would issue the command

cd %SYSTEMROOT%\assembly\GAC
rename Microsoft.Office.Interop.Outlook.OLD Microsoft.Office.Interop.Outlook

The options of the Microsoft Outlook search add-on are quite extensive. It is possible to define a time range for the indexing process and to specify how fast new items should be added to the index.

Lookout will automatically index the contents of attachments with the endings txt, doc, html, htm, xls and ppt. My Document folders can be added to the search as well as additional files, folders and Microsoft Outlook folders.

Lookout is a fast lightweight Microsoft Outlook search add-in that’s way faster than other solutions like Google’s Desktop Search tool.
