Hello Yancel,
If I am understanding you correctly you have an old inactive user. When you onboard a new user you rename the old user to the new user basically giving them access to everything you described above.
Now your questions is there a way to tell what the old user original name?
If I have this correct this is currently not possible. Best practices would be to set old users to delete status and provision new users with new profiles.
