MUC chat, user repeately receive offline messages

Hello

currently I use openfire 3.8.2, for MUC chat, when user becomes offline for a while and then re-connect, user can normally receive offline message,

now suppose that after user is reconnected, and there is no more message sent for the MUC room, then if user re-connect again, user still get the same message, is there any way to ignore the repeated message for openfire? thanks in advance

It’s probably due to the history request, which is sent by your client.

Maybe you can also try to set something in “Group Chat” => “Group Chat Settings” => “History Settings” (“Don’t show history”)
