Xbox app won't let me sign into the correct account

for me the xbox beta PC app will open and when I click sign in, it signs me in with the correct account, and then I close the pop up window and the app is not signed in. I can hover over the sign in drop down and do it 500 times but it never actually lets
me sign in.

It says when I try to download it 'This email address isn't linked to a Microsoft account. Make sure it's correct, then enter it again'. I know its correct though and it won't even let me sign into my account on Xbox.com.

Correct but when I do that the app says I need to sign in to a certain account that was created and then deleted. I have a new adult account that the console is signed into, but the app wants to sign into the old profile. That is the only profile that the app asks for and won’t let me link to it. My console is signed into a new profile but app wants to link to old profile that doesn’t exist anymore

Hi Lewi! My name is Darhyl and I’d be more than happy to help you with your query.

I'm sorry you are experiencing this with your Microsoft account. No worries, let me help you sort this out.

It's important to note that this is a public user-to-user community forum, and none of us here work for Microsoft.

Based on the description you provided, it is not possible to overwrite an account data with a new account however in your case, your Xbox account that has the saved data and achievements is actually associated with a different email address.

To confirm this, sign in to your account on account.microsoft.com > payment and billing > order history and check if you have your purchased transaction showing up there.

You can also check your subscription history on account.microsoft.com > services and subscription.

Also, kindly confirm the gamer tag of the Microsoft account you are signing in to if it matches your Xbox account's gamer tag by signing on to account.xbox.com > then check the gamer tag showing up at the right top corner of the page.

If it's not there, try to sign in to your other email addresses that you know of on account.microsoft.com or account.xbox.com in order to find the email address associated with your Xbox account.

Thank you for your kindness and understanding! Please feel free to let me know if you need anything else.

Best Regards,
Darhyl

You mean like, it would not show the "Sign in" window? Then that fixed it?
