Managing personal Outlook.com account settings, security, and privacy
Hey there! Nice to meet you!
Since you mentioned that you haven't signed in to your account since 2023, I'm afraid your account may have already been deleted/closed due to inactivity.
As stated by Microsoft, accounts that have not been signed in or have been locked for more than 2 years will be deleted due to inactivity, and they can no longer be recovered: https://support.microsoft.com/topic/microsoft-account-activity-policy-7c0a9fa7-0982-b7c6-fd72-df852b63699f
Thank you for your understanding.
Best regards,
Darhyl
