"Official comments on Outlook 2007 requiring Windows Desktop Search:
"Outlook has worked closely with the MS Search team to develop a version of our Instant Search functionality that leverages the new Windows Desktop Search 3.0 platform. These changes have required a significant investment in converting the underlying architectures of the Outlook application and as such have introduced changes into the end-user experience, specifically around configuring the new Outlook 2007 application and the need to install Windows Desktop Search 3.0.
Windows Desktop Search (WDS) 3.0 is a native component of Vista, and is being shipped separately as a system component through Windows Update for Windows XP and Windows Server 2003 users. WDS is a system service that indexes file, email and other content in order to provide fast searches over content and properties. It is an upgrade to all previous 2.x versions of Windows Desktop Search you may currently use.
We will be shipping Outlook 2007 with a new version of Instant Search technology that is built on top of WDS and is dependent on its presence for search to work. B1TR included a native Office indexing component. In order to provide a consistent search experience across the Windows Explorer, Office applications and any others utilizing Windows Desktops Search, and to optimize system resources, we have decided to build on a single, unified indexing component for Windows. The result of this work will be in Outlook 2007 Beta 2, and therefore require installation of WDS 3.0 at boot time." ""Windows Desktop Search has been installed for a few hours already and mail is still not indexed, so searching in Outlook 2007 does not show any or all of the results.""
