|A Lync Online customer can have multiple domains, including the tenant domain of the account and one or more individual domains hosted by the tenant. You can federate with the tenant domain, one or more of the domains hosted by the tenant, or both the tenant and any hosted domains. If you want to federate with more than one of the domains, the administrator of the Lync Online customer must enable federation for each of the domains to be federated.|
