Flexible Offline Message Retrieve shows Disabled

why shows the Flexible Offline Message Retrieve when I open up a user session Disabled?
Both Offline Messages and Monitoring Plugin are enabled.

Thank you

This is a bit of an outdated feature. It will be “true” only if the user requested to not receive offline messages when sending an available presence. The user may send a disco request with node “http://jabber.org/protocol/offline” so that no offline messages are sent to the user when he becomes online.
