I can’t message

Maybe problem with Xbox LIVE services. Maybe you have BAN on communication.

Check your privacy settings and make sure you can receive messages from everyone/your friends.

Could be a problem with your network, thats happened to me lately and I either reset my router or just keep gaming and it will work normally. Try going to settings and checking your network connection to see if everything is good and maybe reset the router
if you are comfortable with that. It might not be a 100% fix but its worth a try. Is this the first time it has happened?

currently there is a problem with messages and Xbox Live Team its working to fix this ASAP!

Regards!

Hello Playah!

Let's start with some chat solutions here:

Before you send and receive messages, also referred to as chats, consider choosing who can communicate with you by text and voice—on Xbox Live and in multiplayer games outside of Xbox Live. Do this by pressing the Xbox button on
your controller to open the guide, then select System > Settings > Account> Privacy & online safety > Xbox
Live privacy > View details & customize > Communication & multiplayer.

Note Group messages (messages to more than one person) sent before the May 2019 update will not be available after May 2019. We apologize for any inconvenience. To save copies of important group messages, do the following:

1. Sign in at support.xbox.com.
2. Select your gamertag in the top right of your browser, then select Xbox Profile > Messages.
3. Choose a message to save, then copy and paste its contents into email or a file to be saved.

To receive messages

Messages you receive from friends and other people you’ve exchanged messages with will appear among your chats.

New messages from people not already on your friends list will appear under

Message requests.

Give these a try and let us know the results!
