Avoid Cluttering the Activity Timeline with Internal Activity
Salesforce continues to add your default internal domain to the
Excluded Address list. Now you can’t delete the default internal domain from the list. By keeping
the timeline focused on customer interactions, the timeline is free from noise and performance
remains high.
Where: This change applies to Lightning Experience in Essentials, Professional, Enterprise, Performance, and Unlimited editions.
How: You can see which internal domain was automatically added to the Excluded Addresses list. From the Einstein Activity Capture settings page, click the Excluded Addresses tab. The delete option is no longer available next to the default internal domain.
