Guys why i can't join in world of my friends on Minecraft?

Hi there Mr. L, my name is Gerardo, and I'm an Xbox player, just like you. I'll be happy to assist you with any questions or concerns you may have.

If this problem only occurs when playing Minecraft Preview and not when playing regular Minecraft, as you mentioned, then it will be necessary for you to contact the game's dedicated support team so they can assist you. They are the ones responsible for helping with these kinds of issues with the game.

You can reach out to them through the following link:

I appreciate your understanding and wish you good luck!

Kind regards,
Gerardo.

we did adjust our accounts, and by the way, one of my friends couldn't adjust his account, he said the "log in" button in xbox.com doesn't work, he said he can't click it.

If your online safety and online settings are well adjusted as well you shouldn't be facing any issues. To be completely sure, make sure you both follow the steps mentioned on this link to adjust the settings => Manage Xbox online safety and privacy settings | Xbox Support.

If the issue still persists, then perhaps your friend has some restrictions on his in game account and not the Microsoft account. In this case he will need to check further with the developer of the game. He can submit a request here => Submit a request – Home (minecraft.net).
