To enable Lync users in your organization to communicate with users of a Microsoft Lync Online 2010 customer, you must have completed the following steps:
Met all prerequisites. This includes deploying your internal and edge servers, enabling federation support for your organization, and setting up user accounts. For details, see Prerequisites for Federating with a Lync Online Customer.
Configured domain access support in your internal deployment. This includes creating a host provider entry and configuring your deployment to allow access from the Lync Online customer’s domain. For details, see Configure Federation Support for a Lync Online Domain.
Configured your user accounts to support federation. For details, see Configure User Access for Federation with a Lync Online Customer.
After you complete all of these steps and the administrator of the Lync Online 2010 customer completes all configuration of their online services to support federation with your organization, verify communications by testing communications between an internal user in your organization and a user of the Lync Online customer. If communication is not successful, use the Logging Tool from your Edge Server to capture log and trace files in order to troubleshoot the problem. For details about using the Logging Tool, see Open Lync Server Administrative Tools in the Operations documentation. For details about the Logging Tool, see the Lync Server 2010 Logging Tool documentation on the TechNet Library at http://go.microsoft.com/fwlink/p/?linkId=199265.
