Remove email address without deleting it on xbox live

Hello, My name is Jesse. I'm an Independent Advisor and a member of the Microsoft community and I'd love to assist you today.

I'm afraid there isn't a way to permanently remove her account. Removing it will delete access to your games, apps and game progress tied to the account.

I know the email address I used to create the XBOX Live account - [mod removed]. I tried logging into XBOX Live with this email address without success. Is that the information need?

if your email address is a Microsoft email (@hotmail, @live, @outlook) then you wont be able to remove your account from the Xbox account.

removing Microsoft email accounts from Xbox accounts permanently deletes the email account and you will no longer be able to access it

all you can do is add an alias email address then promote that to be the main email address.

if the email address is a Microsoft email (eg; @Outlook, @Live, @Hotmail) then it is important that you do not remove it from the Xbox account after adding an alias and promoting that to the primary email.

removing a Microsoft email address from an Xbox account permanently deletes the email account and it will no longer be accessible along with anything else that uses that email (eg; Office365)

Thank you for the suggestion, but this is what myself and Microsoft/Xbox technical support tried over chat. Because the email address I want to remove is an outlook.com address, removing it from Xbox Live would also permanently delete the email address itself.

Here is a Microsoft help topic that mentions this as well:
