Skpe dirty chatrooms
An Auditorium is a type of chat room where only Presenters can post, but everyone can read.
Who can access and manage chat rooms depends on user roles as follows: You use the New-Cs Persistent Chat Room cmdlet to create chat rooms and the Set-Cs Persistent Chat Room cmdlet to configure an existing chat room, including adding users to the chat room.
If a chat room is disabled, its membership list and other settings are preserved.
As an administrator, you can enable a room that has been disabled, and you do not need to manually re-create the settings.
Before you attempt to manage chat rooms, be sure to read Persistent chat categories, chat rooms, and user roles in Skype for Business Server 2015 and Manage categories in Persistent Chat Server in Skype for Business Server 2015.
