Delete rooms and leave rooms
When leaving rooms, they no longer appear in the room list (left column). If the last person in the room leaves, the room is archived for 7 days. After that, is it deleted permanently.
As room administrator, you should “kick” (remove) all members of the room first. Then you should leave the room as the last person to initiate the later deletion by the server.
An export of the room history (e.g. into a .txt or .html file) is not yet possible: https://github.com/vector-im/element-web/issues/2630
