Hello BM_013,
Welcome to Microsoft Community.
I am a Microsoft user just like you, I hope you are well.
Sorry for the inconvenience. However, as a user, you cannot recover an account that has been deleted by the account administrator. This is simply impossible.

Please let me know if you need more assistance.
