lebih mudah untuk menage account email user
The Google Apps administrator control panel has always enabled you to create Google Apps accounts and email addresses for your users, and to control which Google Apps services they can use. In the past, all of your users were created equal: they all had email addresses at the same domain and they all had access to the same set of services.
With the new version of the Google Apps administrator control panel, you can organize your users into multiple domains and organizational units. These options provide you with finer control over each user’s experience: users in different organizational units can have access to different sets of Google Apps services. — > permalink
