About the Organization Hierarchy
To best manage users, you can divide them into groups called organizations (or
orgs, for short). An org can be configured to give its users specific services or
management control, such as a support address, email policy, or administrator.
You can also create sub-organizations (or sub-orgs) below an org to create a finer
level of control within a larger group. The resulting hierarchy is called your
organization hierarchy.
There are several types of organizations:
• Account Administrators organization, which resides at the top of the hierarchy
and is the location of your top-level account administrator.
• User organization, which provides a group of users with common settings,
services, and administrative control.
To view your orgs and manage their settings, see “About Organization
Management” on page 35.
Account Administrators Organization
At the top of the organization hierarchy is your Account Administrators org, named
“Your_Domain Account Administrators.” The Account Administrators org is set up
when your account is created and has your top-level account administrator.
Do not add users to the Account Administrators org. Normally, the Account org is
not modified.
User Organization
User organizations are where user organizations are where your users receive
email protection, and also where your domain is associated.
