Timeline

The timeline is a control on Dynamics 365 model-driven app forms that shows all activities, notes, and posts related to the current record in chronological order. It's the central history view on a Customer, Contact, Opportunity, Case, or Lead — every email, phone call, meeting, task, and note in one scroll. Users can filter by activity type, date range, owner, or status. New activities created from the timeline auto-link to the parent record. Timeline configuration (which activity types appear, default filters, sort order) is per-form. The timeline replaced the older "Activities" subgrid pattern as the recommended way to display interaction history; it's user-loved when configured cleanly and scrolling endlessly through unfiltered noise when it isn't.
