Before Outlook Live users can access IM and presence information by using Web Service Provider, each user must be enabled for Office Communications Server. This requires that the Office Communications Server administrator use the Active Directory Users and Computers administrative tool. The functionality that an administrator needs to use to enable an Office Communications Server user is available in the Active Directory Users and Computers snap-in only if the Office Communications Server 2007 R2 administrative tools are installed on the computer.

By default, the administrative tools are not installed. Office Communications Server administrators have to install the tools by selecting the appropriate setup option from the Office Communications Server 2007 R2 setup. For installation instructions, see “Installing and Using Administrative Tools” at
