I am using Outlook 2007 on my new laptop that is running Windows 7 Ultimate. When I first received the laptop I decided to disable Windows Instant Search because in the past it has always slowed my computers down so much it wasn’t worth having it enabled. I was messing around with the Outlook 2007 settings and noticed that Indexing and Search was not available to configure because it was greyed out. Needless to say I wanted to give Windows Instant Search a shot so I could have these features available in Outlook 2007. Below is how I enabled Windows Instant Search and verified Outlook 2007 indexed various folders and messages on Microsoft Windows 7.
