This guide describes the tasks necessary to configure your Lync Server 2013 environment for interoperability with Lync Online, and then to move users from your on-premises deployment to use Lync Online.

You will need to have the following applications and utilities installed to complete the tasks for configuring a deployment for hybrid. The installers for these files are included on the installation media provided for your deployment, as well as at the links included in the following list.

• Active Directory Federation Services (AD FS) 2.0

• Directory Synchronization tool (DirSync.exe)

• Microsoft Online Services module for Windows PowerShell

• Microsoft Online Services Sign-in Assistant (msoidcli-7.0.msi) is included with the Desktop Setup for Office 365, which can be obtained from the Downloads page linked to from the Admin portal.

When you are asked to provide your administrator credentials, use the username and password provided to you as the administrator account for the Office 365 tenant that was created for you. You will also use these credentials when you configure Active Directory Federation Services (AD FS) 2.0, Directory Synchronization, Single sign-on, and federation.

Administrators now have the ability to use Windows PowerShell to manage Lync Online and their Lync Online user accounts. To do this, you must first download and install the Lync Online Connector Module from the Microsoft Download Center (http://go.microsoft.com/fwlink/?LinkId=294688). For more information on downloading, installing, and using the Lync Online Connector Module, and for detailed information on using Windows PowerShell to manage Lync Online, see Using Windows PowerShell to Manage Lync Online.
