Lync 2010 Client Install "Cannot sign in Server Temporarily Unavailable"
We have been able to install to machine that are external to our network but the users have an AD account and they have logged into Lync client without issue. However, we have a few that throw the Cannot Sign in Server Temporarily Unavailable.
We have done the manual configuration for External/Internal and the same error.
Also, noted the TCP selection is grayed out.
Anyone see this before and know of a fix?
