Can I block all party invites/messages

Hi Sophie!

Sorry to hear about that. Please try the solutions below to change your account privacy options.

Press the Xbox button to open the guide, and then go to Profile & system.
Select Settings > Account > Privacy & online safety > Xbox privacy > View details & customize.
Select Communication & multiplayer, and then review the settings for the following:
Others can communicate with voice, text, or invites
You can communicate outside of Xbox with voice & text
You can use video for communications

I recommend just blocking communications. Then they won;t be able to communicate with you at all, meaning no messages, game invites, party/private chat invites, etc.

Open network settings. Not blocked or banned and couldn't send message to anyone including people I have never messaged. I can still send party invites/game invites and receive them the issue is solely with the messages.

Hi everyone. I am not exactly sure what fixed this for me but it could have been that a 24 hour block reset something for me. It may help getting a 24 hour block yourselves to try and resolve this issue. 24 hour blocks are not bans like communications bans.
So even if you get this block, it won't go on your record and you won't lose any privileges for getting this block such as Xbox live ambassadorship as these blocks are not enforcement action and is done automatically by the Xbox live system. In order to get
this block, you must exceed your daily limit of messages. The best way to do this it to go to your friends list and send party invites in quick succession to all your friends, perhaps multiple invites to each one as messaging would take too long. Party invites
are considered as messages in the Xbox live system. It is best to tell all your friends first so that they know what you are doing. Make sure you don't do this to the public or recent players. Once you get the block, your messaging situation will be the same
as with people not on your friends list except this time you will not be able to send messages even you keep spamming the send message button/invite to party button. You will now not be able to send messages or party invites for a 24 hour period to anybody
including your friends. Game invites, Friend requests, Party chat invites, Video Kinect invites and in game communications will still work though. Once the block is over, there will be no remaining effects of it. No points added to your account or anything
put on your record or reputation, it is just temporary. Hope this helps!

The Block feature I believe only stops game and party invites, chat requests and messages.
