Notification settings

You can configure whether users in your organization receive email notifications on the Notifications tab of the Settings page.
By default, users receive all email notifications. You can change the default for the organization and reset all users to the organization default setting. The organization default setting applies to new users and users who haven't personalized their settings.
To configure the organization default, set the property Enable Email Notifications for Organization. The following image shows the Notifications tab with email notifications enabled for the organization:
Note: All users can check whether email notifications are enabled and personalize their configuration in their user settings.
