You must configure the user accounts of all the users in your organization in order for them be allowed to communicate with federated partners. This configuration is applied for all federated partners, including any Microsoft Lync Online 2010 customer domains with which you support federation. For details about configuring federation support for user accounts, see Configure Policies to Control Federated User Access and Assign an External User Access Policy to a Lync Enabled User in the Operations documentation.
