Banned from editing and not from xbox parties

You would need to go to http://enforcement.xbox.com to see if there is any information.

I have and it doesn't say that I am banned from xbox parties.

When action is taken against your account, you should receive an email telling you the details, plus you can also sign in here to get more info: -

https://enforcement.xbox.com

Nobody here has access to the required systems to see what exactly is happening with your account, so if you haven't checked the enforcement site already, I would do that.

You'll never be given the name or gamertag of whom filed a complaint. The only way of getting any information in regards to your one day suspension is to post a thread on the forum the member above linked and a member of Enforcement will get back to you
in time. After reading several threads in that forum you'll see that you'll receive nothing more than a generic monotonouse post with little explanation.

Either way, I wish you luck in getting to the bottom of it though.

If you're talking to friends over Live and you say something that would cause the enforcement team to ban you, then yes.
