According to the Microsoft Learn documentation on Who Knows Whom (WKW), the enhanced WKW feature uses data directly from Exchange to identify and establish relationship connections. To enable this functionality, Server-Side Synchronization (SSS) must be properly configured.

Once WKW connections are established, all related emails are synchronized into Dynamics 365 and displayed in the timeline. However, not all emails may be relevant to business activities, and some may not need to be tracked within Dynamics 365.

To address this, it would be highly beneficial to provide users with the ability to configure which emails should be tracked in Dynamics 365 or excluded from the timeline—while still allowing the enhanced WKW feature to function effectively in the background.
