Managing personal Outlook.com account settings, security, and privacy
Hello,
May I please know when was the last time you were able to sign in with your @hotmail.com account successfully?
According to the Microsoft account activity policy, if you haven't signed in with your Microsoft account for more than 2 years, your account will be put into an inactive state and will be closed.
You cannot even use the Account Recovery form to recover your account.
