This article provides guidance for telcos and hosting or service providers that currently have hosted or on-premises Exchange deployed with an organizational unit (OU) for tenants. The OU structure in the Lync Server 2010 Multitenant Pack for Partner Hosting is predetermined, and cannot be changed. If you need to install it into your environment and use your existing OU for tenants as the root OU for the Lync Server Multitenant Hosting Pack, you can use the following procedure.

You can change the root organizational unit (OU) when installing the Lync Server 2010 Multitenant Hosting Pack in an Active Directory environment that already has an organizational unit for tenants, or when you want to change the root tenant OU for any reason. This procedure describes how to use ldp.exe to change the otherWellKnownObjects attribute to point to the root tenant OU.
