[Postini Admin Console] Orgs and Users tab [Google Admin Console] 
Review your orgs and org structure After your service transition is completed, you may want to review your orgs and org structure to make sure that your new setup is satisfactory to you. You may also want to review the various settings, such as Content compliance, Attachment compliance, and Receiving routing for each OU. (For instructions and details about the different settings within the Google Admin console, see the sections below.) If you want to modify or fine-tune your org structure in the Google Admin console, see Create an organizational structure, Add an organizational unit, and Modify the organizational structure. Note: If your Postini configuration includes just one account org, one email config, and one user org, you will see just one OU in the Google Admin console when you first log in. In Google Apps, the account org and email config org are not necessary, so the org structure will be simplified for you. If needed, you can add sub-organizations. See Create an organizational structure.
