The eDiscovery Site template is available to Office 365 and SharePoint Server 2013 editions. It has been included due to its expected popularity and usage. If you are not using Office 365 or SharePoint Server 2013 this section does not apply. In this task, we will walk through the process of using the eDiscovery Site template to create an initial eDiscovery Center in SharePoint 2013.
From the Admin Center for your Office 365 instance, at the right end of the toolbar, click the Admin menu.
On the menu that appears, click SharePoint.
In the SharePoint Admin Center, on the ribbon, click the Site Collection tab, and then click New.
On the menu that appears, click Private Site Collection.
On the New Site Collection page, enter a title for the eDiscovery Center, a URL that will be used to access the site under your main URL, and a language for the new site.
Click the Enterprise tab.
Select eDiscovery Center.
Specify the appropriate Time Zone.
