Cannot log into Microsoft Live or Xbox account using my sons login

Hello Anders, this is Manuela. I'm an Independent Advisor and community user like you, ready to assist with this.

I’m sorry to hear you’re having some trouble when trying accessing to your son’s profile. Let’s try to sort this out.

However, before that, I would like to ask the following questions:

Is this problem occurring on PC, Xbox console, or everywhere?
Are you able to log in to your son’s account by using the link below?

SAME SITUATION

I created a XBOX LIVE account for my son over a decade ago. I used my work email address when I created the gamertag. Back then Microsoft's services were not lumped under one login (that didn't even exist). When Microsoft deployed their one login system they
merged my son's Xbox Live account into my work Microsoft account.

Now my son is an adult. We need to transfer HIS Xbox Live gamertag to HIS Microsoft account.

This is idiotic.

This happened to me once before and is now happening again. Something has run ammock with Xbox Live - I can log into my acount via the web, but cannot login to xbox live on my console. I changed my password and still cannot login. Non of the other accounts
on my xbox are working either. Microsoft needs to fix this recurring issue!

Sorry, I misunderstood. My Microsoft store account had to be logged into my sons PC user and Xbox login.

It now works! Thanks for your help!

Hi Georges,

thank you for your answer. I disagree. The problem is with a Microsoft account within minecraft. The issue is definitely with Microsoft.

In Minecraft on switch there is a button to logout from Minecraft. When you login again, the authentication of the first Microsoft account which was logged into is prompted. There is no possibility to change the Microsoft account.

There is an additional button "Delete Microsoft account login data". If this is pressed you are asked, if you are sure. If you press yes, nothing happens. Nothing has changed with login either.

Can you help us, please?

Issue is, I connected the Switch Minecraft version with my adult Microsoft account. Now my son is old enough and I want, that he logs into the switch with his own account. But I cannot change the Microsoft login account of switch minecraft. :-(

Best

Mathias
