i saw a message on my xbox one about the fact i cannot send messages because of my behaviour

According to enforcement I am not banned, though I still cannot send any private message. It says "En raison de votre comportement passé, vous ne pouvez pas envoyer de message."

which mean "Because of your previous behaviour, you cannot send any messages"...

It's not behaviour I'm talking about. People don't have to send messages if they don't want to, so maybe it's just that no one is sending messages.

can anyone help me i've I think i've been banned.

This is what I think is what happened. I was plying one last crucible match (pvp match) on destiny and when I finished I turned my xbox off and went to sleep the next morning I couldn't talk to anyone in a party or send anyone a message on xbox, but when
I tried to send a message to one of my friends it said you cant send a message due to a bad behaviour and think this is because got mad that they lost and reported me. does anyone know how to fix my problem or how I can get unbanned?

Hey there Hayden!

Sorry to hear that you're experiencing this difficulty.

If you don't mind me asking, are you trying to send messages on the Xbox app or through the console?

For either scenario, it's best for you to start off with the steps outlined on our support page entitled

Why can't I send messages from my Xbox One or the Xbox app?

When you get a chance, give those steps a try and let us know if that helped you out.

Alternatively, if it persists, let us know how you're sending them so that we could maybe get to the bottom of what's going on.

Hope this helped.

Thanks for reading!

Have you checked to see if there is some enforcement action against your account?
