Try checking out https://account.xbox.com/en-US/Settings

hi, I’m trying to turn on online multiplayer on Microsoft Xbox setting and it still says you can’t join his realm because how your account is set up do you know how to turn on online multiplayer NEVERMIND it works

In the settings of your world, did you allow multiplayer?

Also, do your online and privacy settings allow Multiplayer (you can check that at
https://account.xbox.com/settings). Also your friends also need to have Multiplayer allowed in their online and privacy settings, and they need to be able to see creations of other
users.

How do I change my online preferences so that I can play multiplayer online.

Might want to check the Privacy and online settings for her Microsoft account on the website. Check if the multiplayer setting is on allow.
