Hello @soqoor ,
Welcome to Microsoft Q&A
Do you have access to the email that registered with Office 2024?
If yes then it better to use that email because the activation code is permanently tied to the Microsoft account used during the first redemption. This is by design for security and license management. Also You cannot merge or move licenses between accounts.
I hope this answer your issue. Feel free to reply to this post if you need further assistance.
