Can I switch an email without messing up the account?

Hi and thanks for reaching Microsoft Xbox gamer's community. My name is Josef.
I'm an Independent Advisor and a Microsoft Xbox user like you.

Hope you're doing great today Cool

Sorry to say but that's not possible. If you delete your mom's email youre going to delete their outlook inbox

My Xbox account is under my mom's Microsoft account. I was wondering if I was able to put my email in there and delete hers from it so it would be fully my account, without messing up her email or account.

Unfortunately not. Changing the primary alias (your moms microsoft email) with your own would cause her Microsoft account to be permanently deleted and would never be able to use the same email to create a new one.

Warning When removing an email alias that’s connected to a Microsoft domain (such as @Outlook.com, @Live.com, or @Hotmail.com), that email is completely deleted from our systems and can’t be used to send or receive emails. It won’t be available for use again as an alias on another account. Microsoft doesn’t recycle email addresses, so it can’t be reclaimed at a future time.

Hello, Karen!

You should be able to create a new Microsoft account and sign in with that. You should cancel any subscriptions on your mom's account and then start a new one on the new account.

If you think this would work for you, please let me know and I can guide you through that.

Otherwise, please let me know if you have any questions.

Trying to sing in to main account in xbox live.com but it takes me to a mess up account associated with the same email how can I fix this?

You can switch without fear! The most important thing about your account is not your gamertag, but your email.
