In fact, in some cases it might not be possible +to recover at all:</p> +<ul> +<li>If the room was invite-only, your users will need to be re-invited.</li> +<li>If the room no longer has any members at all, it'll be impossible to rejoin.</li> +<li>The first user to rejoin will have to do so via an alias on a different +server (or receive an invite from a user on a different server).</li> +</ul> +<p>With all that being said, if you still want to try and recover the room:</p> +<ol> +<li> +<p>If the room was <code>block</code>ed, you must unblock it on your server.

These will need +to be restored manually.</p> +</li> +<li> +<p>Users on your server that were in the deleted room will have been kicked +from the room.
