Hi,

You have to unkink any email from your old gamertag.

Then unlink the actual gamertag with your email account.

And finally , link the old gamertag to your email account.

good evening

Your Xbox gamertag is linked to your Microsoft account, but if it was created with an old email address that no longer exists, you will need to create a new Microsoft account with your current email address and link it to your Xbox gamertag.

To do this, follow these steps:

Go to the Xbox website and sign in with your current email address.

Create a new Xbox gamertag if necessary.

Link your new gamertag to your Microsoft account.

Transfer your Xbox Live Gamerscore and Xbox One games to your new gamertag.

As you mentioned that you suspect that this gamertag is linked to one of your old email accounts. I will suggest login to your old email account and change the email address of that one with your new email address as described here https://support.microsoft.com/en-au/help/12407/microsoft-account-change-email-phone-number

Or you can delete or change your gamertag by accessing your old email account first.
