MC1419800 - SharePoint button web part: Add custom Copilot in SharePoint prompts or start Power Automate flows

What and Why:

Microsoft is expanding the capabilities of the SharePoint Button web part beyond static hyperlinks. Organizations can now create buttons that either launch a predefined prompt in Copilot for SharePoint (for users licensed for Microsoft 365 Copilot) or initiate a Power Automate flow. This enhancement supports Personal and Team Productivity and Business Process Automation by helping users access AI-powered experiences and workflow automation directly from SharePoint pages.

Rollout Schedule:

• Targeted Release (Worldwide): Beginning in late July 2026; expected to complete by late July 2026
• General Availability (Worldwide): Beginning in late July 2026; expected to complete by mid-August 2026
• General Availability (GCC): Beginning in late July 2026; expected to complete by late August 2026
• General Availability (GCC High): Beginning in late July 2026; expected to complete by early September 2026

Impact on Your Organization:

Who is affected:

• SharePoint page owners and site editors.
• Users with Microsoft 365 Copilot licenses.
• Users authorized to run Power Automate flows.

Platforms/Services:

• SharePoint Online
• Microsoft 365 Copilot
• Power Automate
• Web

What will happen:

• Existing Button web part links will continue to function without changes.
• Page authors will be able to configure a Button web part to launch a predefined Copilot in SharePoint prompt.
• Page authors will be able to configure a Button web part to initiate a Power Automate flow using a Flow ID.
• Copilot in SharePoint prompt buttons will be available only to users who have a valid Copilot license.
• Power Automate flow buttons can be used by authorized users regardless of Copilot licensing.
• The feature will be available by default once released; no migration of existing button links is required.
• No changes are made to existing Button web part configurations.

Action Required/Recommendations:

No administrative action is required.

Recommended actions:

• Review SharePoint governance and page authoring guidance before rollout.
• Inform SharePoint site owners and content authors about the new Button web part capabilities.
• Communicate to licensed Copilot users that custom Copilot in SharePoint prompt buttons can be added to SharePoint pages.
• Evaluate whether predefined Copilot in SharePoint prompts could streamline common employee workflows and knowledge discovery scenarios.
• Review Power Automate flows that may benefit from direct launch from SharePoint pages.
• Update internal SharePoint training materials or documentation if you provide guidance on page authoring.
• Review licensing requirements to ensure users expected to use Copilot in SharePoint prompt buttons have appropriate Copilot licenses assigned.

Compliance Considerations:

Compliance Area	Explanation
Introduces or significantly modifies AI/ML or agent capabilities that interact with or provide access to customer data	The update introduces a new capability that allows SharePoint page authors to create Button web parts that launch predefined prompts in Copilot for SharePoint. This provides a new entry point for users with a Copilot license to interact with AI experiences grounded in organizational content and permissions.
Provides end users a new way of interacting with generative AI	Users with a Microsoft 365 Copilot license can invoke predefined Copilot in SharePoint prompts directly from SharePoint pages by selecting a configured button, creating a simplified and guided generative AI experience.
Includes an admin control and can be controlled through Entra ID group membership	No new dedicated admin control is described in the announcement. However, access to Copilot experiences continues to depend on existing Microsoft 365 Copilot licensing, permissions, and any organizational controls already used to govern Copilot access, which may include Entra ID group-based license assignment.
Allows a user to enable or disable the feature themselves	SharePoint page owners and authors can choose whether to configure Button web parts as traditional links, Copilot in SharePoint prompt buttons, or Power Automate flow launch buttons on pages they manage.
