MC1282571: Copilot entry point changes in Excel

[Introduction]

We’re updating how users access Copilot in Excel to provide a clearer, more consistent, and more intuitive experience across Microsoft 365 apps. These changes consolidate multiple Copilot entry points into a single, predictable location and establishExcel Edit Mode in the right-side chat pane as the primary Copilot interface. This update improves discoverability, simplifies user workflows, and aligns the Excel Copilot experience with other Microsoft 365 applications.

[When this will happen:]

• General Availability (Worldwide): Rollout begins in late April 2026 and is expected to complete byearly June 2026.
• General Availability (GCC, GCC High, and DoD): Rollout begins in early October 2026 and is expected to complete by late October 2026.

[How this affects your organization:]

Who is affected:

• All users of Microsoft 365 apps for Excel on Windows, macOS, and the web with Copilot enabled.
• A Microsoft 365 Copilot (Premium) license is required to use this feature.

What will happen:

• Some Copilot entry points that appear when selecting a cell or opening the right-click menu will be removed.
• A single, consolidated Copilot entry point will appear in a consistent corner location within Excel.
• Screenshot: Updated Excel entry point:
• TheExcel Agent in the right-side chat pane becomes the primary interface for Copilot prompts and responses.
• Copilot availability, licensing, and existing admin policies remain unchanged.
• The feature is on by default for users who already have Copilot access.

[What you can do to prepare:]

• Inform users about the updated Copilot entry points and chat-based experience in Excel.
• Update internal documentation or training materials if you reference specific Copilot buttons or menus.
