[Introduction]
Microsoft is introducing a unified plus (+) menu to make it easier for users to add grounding, tools, and sources when prompting in Microsoft 365 Copilot. Grounding refers to the content users connect to Copilot-such as files, sites, or other organizational data-that helps improve response relevance. This update consolidates related actions into a single menu, improving discoverability and streamlining the workflow for adding entities or updating inputs. This simplified menu will be available for Copilot Chat users (without a Microsoft 365 Copilot license) and Microsoft 365 Copilot users (with a Microsoft 365 Copilot license).

Note: The Tools menu will be consolidated under the unified plus (+) menu and no longer exist as a separate menu in the prompt box after this change.
[When this will happen:]
General Availability (Worldwide): Rollout begins in early March 2026 (previously late February) and is expected to complete by mid-April 2026 (previously mid‑March).
