What the notice says

Microsoft’s text, with source markup removed
Updated August 3, 2026: We have updated the timeline. Thank you for your patience.  What and Why: PowerPoint Copilot on the web is introducing support for personal, user-defined custom skills stored in OneDrive. Users can upload skill folders containing a SKILL.md file to a designated OneDrive location, and those skills will automatically appear in the Copilot Skills menu within PowerPoint for the web. A new Manage Skills experience will also allow users to enable or disable individual skills directly from the Copilot pane. This enhancement supports personal productivity by enabling users to tailor Copilot to their specific workflows and presentation needs while maintaining control over which skills are available during Copilot interactions. Rollout Schedule: General Availability (Worldwide): Rollout begins in late July 2026 and is expected to complete by early August 2026 (previously late July). Impact on Your Organization: Who is affected: Users licensed to use Microsoft Copilot in PowerPoint for the web. Users who create or use personal custom skills. Microsoft 365 administrators supporting Copilot deployments. Platforms/Services: PowerPoint for the web Microsoft 365 Copilot OneDrive What will happen: Users can upload skill folders containing a required SKILL.md file to a designated OneDrive location. Uploaded skills are personal and visible only to the user who uploads them. Eligible skills automatically appear in the Skills menu within PowerPoint Copilot on the web. Users will have access to a new Manage Skills experience from the three-dot menu in the Copilot pane. Screenshot 1: Users can open Manage skills from the three-dot menu in the PowerPoint Copilot on the web pane: Users can independently enable or disable individual skills. Screenshot 2: Users can enable or disable individual skills from the Manage skills experience in PowerPoint Copilot on the web: Skill availability within Copilot will reflect the user's selected settings. No additional administrator deployment actions are required for the feature to appear. The feature is available by default to eligible users when rollout reaches the tenant. Action Required/Recommendations: No immediate administrator action is required. We recommend that you: Review any internal governance processes related to user-created Copilot skills. Prepare sample skills in the required format with a valid SKILL.md file for testing. Identify pilot users who can validate the experience after rollout. Update internal Copilot adoption and training materials to include guidance on custom skills. Inform helpdesk and support teams about the new Skills and Manage Skills experiences. Monitor user feedback following rollout to understand adoption and governance needs.
