ROLLOUT TIMELINE
Late July–Mid Aug 2026
📢 Official Microsoft Message Center Announcement
(Updated) Add and upload your custom skills to OneDrive from within PowerPoint Copilot (Mac)
Message ID: MC1441781 (Updated)
Updated August 5, 2026: We have updated the timeline. Thank you for your patience.
[What and Why:]
PowerPoint Copilot users can now upload custom skills directly from the Copilot experience and create new custom skills within PowerPoint. Custom skills are user-created instructions that extend and tailor Copilot behavior for specific tasks and workflows. Uploaded and added skills are saved to the user’s personal OneDrive and are available for that user’s personal use in PowerPoint Copilot. This enhancement streamlines skill creation and management by allowing users to customize Copilot directly within their workflow.
