What should you select to enable email notifications for generated reports?

To enable email notifications for generated reports, selecting the option to enable notifications is essential. This feature is crucial as it allows the system to send out alerts and updates regarding the reports directly to users' email addresses. When notifications are enabled, users can receive timely information about report availability, completion, or scheduled runs, which enhances communication and keeps stakeholders informed.

The other options, while potentially relevant in different contexts, do not directly relate to the action of activating email notifications. Allowing external sharing focuses on permissions for accessing reports outside the organization, scheduling email distribution pertains to setting when reports should be sent out rather than enabling the notification feature itself, and using default server settings relates to the configuration of the server rather than specifically enabling notifications. Each of these options serves its own purpose but does not address the core requirement of activating email notifications.
