Enabling advanced search inside Microsoft Office Outlook 2007 requires that you install Windows Search Service on the machine! However, installing this service is not that direct and easy to reach.
To install Windows Search Service on a Windows Service 2008 follow the steps below:
- Go to the Server Manager
- Click on Add Roles
- Select File Services
- Select Window Search Service
- Select the drives you want WSS to have control on
Hope this helps,
