You deploy a server that has Microsoft SharePoint Foundation 2010 installed. Users report that they cannot configure the Alert Me option for SharePoint documents. You need to ensure that users can create alerts. What should you modify from Central Administration?

A.
Configure Send To Connections

B.
Information Rights Management

C.
the Outgoing Email Settings

D.
the Workflow Settings

Explanation:
To enable search alerts
1. Verify that the user account that is performing this procedure is an administrator for the Search service application.
2. Open SharePoint 2010 Central Administration.
3. In the Application Management section, click Manage service applications.
4. On the Manage Service Applications page, click the Search service application for which you want to configure search alerts.
5. On the Search Administration page, in the System Status section, locate Search alerts status.
6. The search alerts status displays as OffEnable or OnDisable.
7. By default, search alerts are turned Off. Click Enable to turn on Search alerts.
The option is now set. Search alerts are sent only if outgoing e-mail is configured. For more information, see Configure outgoing e-mail (SharePoint Server 2010). Users can now create search alerts for search queries that they run. To configure search alerts for search queries, click the Alert Me icon on the Search Results page. The Alert Me icon is located on the Search Results page at the top of the search results pane next to the RSS icon. If search alerts are turned off, this icon does not appear.
