How do I delete an email account I can't find?

Got it figured out on my own, finally. Thanks for your help.

Littleneilnpl, is this second hotmail.com account an alias?

1. Sign in to Manage how you sign in to Microsoft with your Microsoft account. If you’re having issues signing in to your Microsoft account, go to Microsoft account help.

2. Check under the Account aliases section.

If you do not find this account, kindly contact Microsoft support via live chat using steps provided above for assistance finding the account.

Finally figured it out at last. One email address is one MS account. Was able to sign in for her and delete it , thank you.

I was actually describing my wife's situation. She has two (hotmail) email addresses . She wants to permanently remove one of them. She has her own Microsoft account. She can and does receive emails sent to both addresses using Outlook 2021 or using Ourlook.com (webmail). It's the address she wants to eliminate so no more junk mail can be sent to it. I'm not seeing that address anywhere where it can be deleted permanently.
