My microsoft account isnt set up to play multiplayer

Hi my son signed up with my old yahoo email there is no microsoft email hence why i cannot sign into his account. Cannot log into his account as it isnt a microsoft account. Very confused as to how it has been set up in the first place

It says this when I try to play online, “you cannot play online multiplayer because of how your Microsoft account is set up”

I wanted to play Minecraft PS4 servers but when i signed into my Microsoft account i couldn't play servers because of the message that popped up "You cannot play online multiplayer because of how your Microsoft account is set up." please help me resolve
this problem because i have nothing on my account restricting this type of play.

Please send advice quickly as possible.

I have the same issue with my children’s accounts. No matter what settings I change, they cannot play with me on my realm.

This is infuriating especially since it’s only affecting minecraft. I can play other multiplayer games with them, though.

he isnt using a guest account because i set the xbox up specifically with his own account on it, but when i log into my Microsoft account and check under family, his account is linked to my email address.

Hello,

I am trying to play multiplayer on the Xbox S, more specifically cross-platform play. I do not have Xbox live, but I don't need it to play. When I try to join it says that "You cannot play online multiplayer because of how your Microsoft Account is set up"
but all of my privacy settings allow online gaming and multiplayer gaming. My account is also an adult account so it's not like I need permission. I tried everything, restarting my console and router as well as talking to the virtual agent. All of my settings
give permission and I just don't know what the problem is.

Thank you
