Copilot Notebooks: New features coming to Frontier Public

Introduction

We’re introducing several new Copilot Notebooks features to the Frontier Public environment to help users learn faster, create content more efficiently, and collaborate more easily within their organization. These enhancements build on customer feedback and expand how Copilot can reason over notebook content and connected Microsoft 365 resources. Each feature will reach General Availability (GA) on its own schedule following Frontier Public availability.

When this will happen:

• Frontier Public rollout: Beginning March 23, 2026, with broad availability across Frontier Public tenants by March 28, 2026.
• General Availability (GA) (Worldwide): Rolling rollout from early April 2026 through early May 2026. Each feature will reach GA on its own schedule.
• Rollout is gradual; availability may vary by tenant and feature.

How this affects your organization:

Who is affected:

• All Copilot Notebooks users (in the Microsoft 365 app and OneNote) in Frontier Public tenants
