need help with old messages

Hi there,

if you haven't yet, have you tried to see what happens when you send messages via xbox.com or via the Xbox App to see if that makes any difference.

Also be sure to check
http://enforcement.xbox.com to see if any enforcement action on your account could be affecting this

Another thing to check if your account is allowed to communicate with others via settings here:
http://account.xbox.com/settings

If this is a child account then a parental account needs to change these settings.

If this is only happening on the console, then try the following:

1. Remove profile from the console (Make sure you know the account credentials for the account, since you will need them later)
   
2. Perform the manual power cycle steps like mentioned on the following link, be sure to wait at least 60 seconds before powering on again:

3. Redownload your profile ​

If these steps fail, then its best to contact Xbox Support (via Phone or Microsoft Support Chat) at
http://support.xbox.com/contact-us

Let us know the results

Try this:

1. Sign in at
   account.live.com/reputationcheck.
2. Add your phone number, then select Send code.
3. Get the code from the text message sent to your phone, enter it on the webpage, and select
   Submit.
4. If you’re using your Xbox, press and hold the power button for 10 seconds to turn it off, then turn it on and sign back in. If you’re on a PC or mobile device, sign out of the Xbox app, then sign back in.
   

I know this post is kinda old but if you are still trapped I can help. Message me on XBL if you need a hand.

Contact phone support. If you're in the US their number is 1-800-469-9269.

Xbox files are not meant to be saved to a PC and back. There is no legit way of restoring them so they can be used on the 360.
