Turn Instant Search on or off
The Instant Search function in Microsoft Office Outlook 2007 runs on components of Windows Search (formerly known as Windows Desktop Search). If these components are not installed when you start Office Outlook 2007, you will be prompted to download the Windows Search software.
Note Windows Vista and Windows Vista Service Pack 1 (SP1) include the necessary Windows Search components, which means Instant Search is enabled automatically. If you use an earlier version of Windows, you must download the Windows Search software to use Instant Search in Office Outlook 2007.
Turn on Instant Search
To turn on Instant Search, click the message Click here to enable Instant Search in the Instant Search pane. If you do not see this message, you already have Instant Search turned on.
Turn off Instant Search
On the Tools menu, point to Instant Search, and then click Search Options.
In the Indexing section, clear the check boxes under Index messages in these data files.
Clearing the check boxes turns off search functionality but does not remove the Instant Search pane.
Even if Instant Search is turned off, you can still search in Outlook, although performance and functionality will be reduced.
Turn off the prompt for installing Windows Desktop Search
To avoid being prompted to install Windows Desktop Search every time that you open Outlook, do the following:
On the Tools menu, click Options.
On the Other tab, click Advanced Options.
Under General settings, clear the Show prompts to enable Instant Search check box.
Note This check box does not appear if your computer runs Windows Vista, or if your computer has the necessary Windows Search components installed.
