Reset any User Password as an Admin

  4. Select the user whose password you need to reset and a pop up should appear on the right side of the screen.

  5. Click Reset password.

  6. You will have options to have the system Auto-generate a password or you can create one yourself. Choose your option to create the password.

    Note: We recommend that you also check the box to make the user change their password when they first sign in. Have them log into portal.office.com to update their password.
