Can any Minecraft Bedrock worlds be deleted if I remove an alias from my Microsoft Account?

Hi and thanks for reaching Xbox gamer's community. My name is Josef.

Thanks for reaching out! I'm an Independent Advisor and a Microsoft user like you.

I'll be happy to assist you out today.

Hope you're doing great today Jack

First you need to add a new alias to your account, but to do this new alias domain can't be a Microsoft domain (outlook.com, hotmail.com, etc), other than that you're good to go.

When you add the new alias, remove your brother's alias and then you should be fine.

You can learn more about aliases here:

Yeah, you should be good in that case.

Now when you sign in with Microsoft account on Minecraft or another game/service, use the new primary alias

I have already added two of my personal emails (both gmail accounts) as aliases to the account, with one of those being the new primary alias. Should I be good to go?

Hi there YojanWayne,

Thanks for reaching out here in Xbox Forums. I understand there is a question with Microsoft Account Alias.

• If you remove an alias that's an email address from a Microsoft domain (like @hotmail.com, @live.com, @outlook.com, or @msn.com), you're permanently deleting the alias and it can't be associated with any Microsoft account again.
• Make sure you save any info that you want from this alias before you remove it. All your email and contacts for this alias will be immediately deleted from the server and can't be recovered, and you won't be able to access Microsoft
  services like Xbox, Skype, and OneDrive if they use that alias.
• If you're removing a primary alias, you'll need to choose another primary alias before it can be removed. If you’re using the primary alias to sign in to Microsoft services, you may not be able to sign in to these services after you delete
  the alias.
• If you remove an email address from a non-Microsoft domain (like @gmail.com), then it usually becomes immediately available to be added as an alias on another Microsoft account.

For more detailed information about how to add an alias, including why and how to set your primary alias, see the
Manage aliases on your Microsoft account article.

Hope this helps.

When Minecraft stopped working, I used my Microsoft account. And this issue happened after I changed my main alias from E-Mail 2 to E-Mail 1. I can play Minecraft if I log in with my E-Mail 2.

I purchased Minecraft on my Mojang account before the migration, but I don't use my mojang account and that Microsoft account that was migrated to.

With my Mojang account (E-Mail 1) migrated to Microsoft account (E-Mail 4) I bad the Java Edition. With my first Microsoft account (E-Mail 1, now 3) I had Minecraft Bedrock Edition. And with the other MIcrosoft account (E-Mail 2, now 1) I have both Java and Bedrock.

I purchased Minecraft Bedrock Edition on my Microsoft Account (E-Mail 1, now 3) from the Microsoft Store and I purchased Minecraft Bedrock Edition on my Microsoft account (E-Mail 2, now 1) from the Microsoft Store but the Java Edition I purchased from minecraft.net. On my Mojang account (E-Mail 1, now migrated to Microsoft Account with E-Mail 3) I bought Minecraft Java from minecraft.net.
