I can't message my friends

I signed in to my old account and it worked, it still doesn't work on my current account.

Hey there -

I'm not sure who sent you to us however we are unable to lift or bypass the flood ban for messaging. If you are unable to send messages, we recommend checking out >>this
page<< for further information.

Thanks for understanding.

Same thing is happening to me. There must be something going on.

Actually, my brother has been banned 2 times, most recent was 8/29/2016

But why does that affect me?

Hi kaprimek -

Sorry to hear that you're unable to send messages. Let's have you power cycle your Xbox One if you haven't already first.
It might also be necessary to reset your router/modem as well.

Let us know if you're still unable to send and/or receive messages! We're here to help.
