* From the scenario we have: Only users in the human resources department must be able to
access and discover a persistent chat room named HRConfidential
* Select a privacy setting for your room from the three options:
Open – Anyone will be able to find this room (via search), open it, and read and write in (“post
to”) it. Open rooms have no “membership” per se.Closed – Non-members will be able to find this room and see who is a member, but only
members will be able to open the room, read or post to it. (This is the default setting.)
Secret – on-members won’t be able to find this room, learn who has membership in it, or read or
post to it.
* New-CsPersistentChatRoom
Creates a new Persistent Chat chat room. A chat room is a discussion forum that typically
revolves around a specific topic.
* New-CsPersistentChatPolicy
Creates a new Persistent Chat policy at the site or the per-user scope. Persistent Chat policies
determine whether or not users are allowed access to Persistent Chat chat rooms.
