Verwalten persönlicher Kontoeinstellungen, Sicherheit und Datenschutz für Outlook.com
Hi Said,
I understand that you would like to recover the old account, however please note that as per Microsoft account policy they stated that - If you don’t sign in to your Microsoft account at least once every two years, they will close the account due to inactivity. This means you’ll lose access to all Microsoft products and services that require the account.
For more information, you can refer to this link: https://support.microsoft.com/de-de/accounts-billing/manage/microsoft-account-activity-policy
