App Blocks in M365 Copilot

What and Why: App Blocks enables M365 Copilot Chat users to turn their requests and data into rich, interactive experiences directly within the conversation, including calculators, dashboards, forms, planners, visualizations, simulations, comparison tools, and other interactive apps. It helps users move beyond static responses to explore data, adjust inputs, visualize outcomes, and simulate workflows in place, while supporting grounded scenarios where current information can be retrieved and then rendered into an interactive experience. Rollout Schedule: General Availability (Worldwide): We will begin rolling out in late October 2026 and expect to complete by early November 2026. Impact on Your Organization: Who is affected: Users of Microsoft 365 Copilot (Premium) and Copilot Chat (Basic). Platforms/Services: Microsoft 365 Copilot Chat What will happen: App Blocks will render directly within Copilot conversations. Users can preview apps without opening a separate app canvas. The update streamlines the Copilot experience by keeping generated content and previews within the conversation flow. Existing Copilot workflows and prompts continue to work as expected. Action Required/Recommendations: No action is required. You may want to notify your users about this experience update and update any internal training or adoption materials that reference the side-by-side app canvas experience. Compliance considerations: No compliance considerations identified. Review as appropriate for your organization.
