Later, Skype for Business was enabled for Skype for Business on-premises for a single user by using the following cmdlet: Note This cmdlet updates the on-premises MSRtcSipDeploymentLocator attribute for the user to "sipfed.online.lync.com."

Enable-CsUser-Identity "username" -SipAddress "sip:email@example.com"-HostingProviderProxyFqdn "sipfed.online.lync.com"
