I've deployed simple lync 2013 infrastracture. 1 edge, 2 front end, 1 webapp, 1 backend for mssql databases, and AD + CC.
Everything works great except mobility.
When I run Test-CsUcwaConference, Test-CsMcxP2PIM commands following error message displayed:
IIS -> Lync server external and internal web site authentications enabled providers are Negotiate, NTLM.
Please advice me if you have happened this error too.
