The installation of the Google Apps Sync for Microsoft Outlook disables the ability of Outlook to search the Outlook data. When you install the sync plug-in for Outlook, the sync plug-in changes a registry key. This disables Windows Desktop Search from indexing and providing search functionality for all Outlook data, not just the Outlook data being synchronized from GMail. Because Outlook search relies on the indexing performed by Windows Desktop Search, Outlook search functions are broken.
Note Uninstalling the sync plug-in may not resolve the issue.
