Answer 1

The SharePoint Directory Management service connects SharePoint sites to your organization's user directory to provide enhanced e-mail features. The benefit of using this service is that it enables users to create and manage e-mail distribution groups from SharePoint sites. This service also creates contacts in your organization's user directory so people can find e-mail-enabled SharePoint lists in their address books. However, using SharePoint Directory Management service requires more management because it is communicating with Active Directory Domain Services (AD DS).
