Sending, receiving, and organizing email in Outlook.com
Hello, thank you for reaching out to Microsoft Q&A.
May I please know when was the last time you were able to sign in with your old Hotmail 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.
