This table lists the action and what you can and can’t do as a room manager.
A Skype for Business (Lync) chat room “category” is a collection of room characteristics that can be applied to several rooms for convenience.
Every Skype for Business (Lync) chat room has a privacy level, which controls who can find it and who can get into it. Hover over the chat room icon for the room you want to follow, then click the More options button.
The chat room owner sets the privacy level on the Create a room window when the room is first set up. Once you have been granted membership, add the room to your list of followed rooms: 1.
(Rooms with a privacy setting of “open” do not require or allow membership.) That is, you can add members as you see fit (again, as long as they appear in the pool of potential members for the room category that your room belongs to). In Members, enter the names of people to invite to be room members.
