Unfortunately, I cannot provide assistance with recovering a Microsoft account when the email address is unknown. However, I recommend following the standard account recovery process by visiting the Microsoft account recovery page. You may need to provide information to verify your identity, such as any associated usernames or details about your account usage.
If you are unable to recover your account through the standard methods, consider reaching out to Microsoft support directly for further assistance. They may have additional options available for verifying your identity and recovering your account.
