Could you please active the password reset for users from my admin account.

And there is a option available from my user account I have checked, where the user can close/delete the account, is it possible to turn that option off from the user account. I will be using this service mainly for my office employee and will need more user soon, so if some of my employee remove the account I'll lose all the official data, please let me know if there is any solution for this. Thanks.
