Control field synchronization with Outlook
With field synchronization, admins can set the sync direction between customer engagement apps (Dynamics 365 Sales, Dynamics 365 Customer Service, Dynamics 365 Field Service, Dynamics 365 Marketing, and Dynamics 365 Project Service Automation), and Microsoft Dynamics 365 for Outlook fields. You can control synchronization when using either Outlook synchronization or server-side synchronization (Exchange).
For example, a salesperson may want to take personal notes about a contact and not want the notes to synchronize with data available to all users. An admin can set the Personal Notes field for contacts in Outlook to not synchronize Dynamics 365 for Outlook with customer engagement apps so the salesperson's notes will remain private.

Performance and synchronization
Configuring synchronization might have an impact on the time it takes to sync between Dynamics 365 for Outlook and customer engagement apps. You should test your configuration before deploying to ensure satisfactory sync times.
Permissions and synchronization
Role-based security controls access to a specific entity type, record-based security controls access to individual records, and field-level security controls access to specific fields. All these can impact what is synchronized between customer engagement apps and Dynamics 365 for Outlook or Exchange.
Best practice is to review the security settings for these security methods to ensure field synchronization is processes as desired. For more information see:
