Which option allows an administrator to track email delivery more effectively?

Delivery Insights is the most effective option for tracking email delivery because it provides a comprehensive view of the email flow within the organization. This feature offers detailed analytics on email delivery statuses, including insights into successful deliveries, bounces, and delays. By utilizing Delivery Insights, an administrator can quickly assess the performance of email sending and receiving, identify issues in real-time, and improve overall email management.

In comparison, while Email Logs provide a record of email transactions, they may not offer the same level of analytical insights or trends as Delivery Insights. Policies Overview focuses on the configuration and status of policies but does not directly address tracking delivery effectiveness. Connection Reports give information about connectivity and connection states but are more technical and do not specifically analyze the success or failure of email deliveries. Thus, Delivery Insights stands out as the most effective tool for monitoring email delivery efficiently.
