Which of the following is essential for setting up Email Engagement in Dynamics 365 Sales?

Enabling server-side synchronization is essential for setting up Email Engagement in Dynamics 365 Sales because it allows Dynamics 365 to connect with the user's email account in a seamless manner. Server-side synchronization enables bidirectional synchronization of data such as emails, appointments, tasks, and contacts between Dynamics 365 and the user's email system, which is typically Exchange Online or other email servers compatible with Dynamics 365. This capability is crucial for the Email Engagement feature, as it ensures that emails sent and received within Dynamics 365 can be tracked and logged accurately, facilitating better engagement analytics and workflows tailored to customer interactions.

This synchronization allows for automatic tracking of interactions, ensuring that sales teams can see communication history directly within the Dynamics 365 environment. Without server-side synchronization, users would not be able to effectively leverage email tracking and analytics features, which are integral to understanding customer engagement and enhancing sales processes.
