Minecraft mash ups lost because I hjave no accesss to old email address

You'd have to contact support. As long as you can verify that you are the owner of the account, they should be able to get you the email. 1-800-4my-xbox if you're in the US/Canada or
support.xbox.com/contact-us

everythings up and running. i have been hjaving this issue for awile now.

Sometimes you can verify your account using another email address or a mobile number that you recieve a text to. If the email address is lost then try asking the recovery team to change your verification method to a different address or number and to use
a different email address instead of the old one.

Hi, you need the full game of Minecraft to play the mash ups.

I tried to add my other email to my microsoft account but it says its part of a reserved domain, So i cant add it as an alternative account. So another minecraft player is using my email for their minecraft earth account and thats why i cant use it? When
i sign into minecraft earth i come up as princess.cossign which isnt me but when i play on normal minecraft everything is fine, why is there a problem all of a sudden because of playing minecraft earth? Id like to be able to use my main minecraft account on
minecraft earth and not have it come up as someone i dont knows minecraft account. I dont want my email connected to another minecraft account and i also feel bad for the the other person that they might have lost access to their account because of this mix
up or whatever it is, im so confused... please help!?
