Why I Can't Write Messages?

Sorry to hear that, Pursiy!

Please try signing into this page, then input your phone number, and enter the code that the page texts you after that. Do you still see any trouble sending messages afterward?

daft you mod my message? i call microsoft support and them tell me write on forum, now you remove a name of cheater why if sameone want reclaim can't do!

Can you check the following:

Sign in on the Xbox website on https://www.xbox.com

Then click on your account picture and from the menu choose "Messages"

Are you able to see and send messages on the Xbox.com website?

This is a little bit of an update on my situation, I figured out that it's not the account itself that works, but something else because, I added my second account on so that I could see wether it worked or not, and I was unable to send messages in that
account as well, it said the same thing last time as I listed above, so I don't know if it's my internet (even though I have a Ethernet cable connecting it to my router), or it's just plainly my xbox. Thank you for the comments so far, I appreciate people
trying to help.

It might be that you just need to refresh your profile data. Try removing the account from the console, doing a hard restart, hold the power button for 10 seconds while the system is on, and then re-adding the account.
