Will Everything on My Account be wiped if I change Email?

You’ll keep everything just make sure its on your same xbox profile

as long its your main email linked to you xbox account

i have done this myself

So long as you're changing the email on the account you're using you'll be Good.

I've done this myself in the past.

As long as you add the new email account to your current Xbox account, then set it as the primary, then remove the old one, you will be fine.

If you just create a new Xbox/MS account and delete the old one, then you will permanently lose all your digital games and progress.

Hello! As long as you have your saved data in the game (You can see this by going to manage game -> Saved Data, and there should be one with your gamertag), you shouldn't lose any of your data with the game.
