150 Message Security for Google Apps Administration Guide
To set up notifications for an organization:
1. Go to Orgs and Users > Orgs.
2. Choose the organization from the Choose Org pull-down list, or click the
name of an organization in the organization list.
We recommend that you set notifications for organizations that contain your
users. (Although they can be set at the account and email config orgs, those
settings do not apply to any users.)
3. In the Organization Management page, scroll to the Organization Settings
section and click the Notifications icon.
4. The User Notifications page lists the notifications and their settings. You can
turn notifications on or off, and customize the content of notifications. The first
step is turn on notifications. See “About Customizing User Notifications” on
page 383 for customizing the notification content.
