Message Center
What changed since this version
Updated August 3, 2026: We have updated the timeline. Thank you for your patience.
What and Why:
PowerPoint Copilot for Mac is introducing support for personal, user-defined custom skills stored in OneDrive. Users can upload skill folders containing a required SKILL.md file to a designated OneDrive location, and eligible skills will automatically appear within the Copilot Skills menu in PowerPoint. Users will also be able to manage individual skills through a new Manage Skills experience in the Copilot pane.
This enhancement supports personal productivity by enabling users to tailor Copilot to their specific presentation workflows 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 byearly August 2026 (previously late
July 2026July).
Impact on Your Organization:
Who is affected:
- Users licensed to use Microsoft Copilot in PowerPoint for Mac.
- Users who create or use personal custom skills.
- Microsoft 365 administrators supporting Copilot deployments.
Platforms/Services:

What will happen:
- Users can upload skill folders containing a required SKILL.md file to a designated OneDrive location.
- Uploaded custom skills are personal and visible only to the user who uploads them.
- Eligible skills automatically appear in the Skills menu within PowerPoint Copilot on Mac.
- Users will have access to a new Manage Skills experience available from the three-dot menu in the Copilot pane.
- Users can independently enable or disable individual skills.
- Skill availability within Copilot reflects each user's selected settings.

- Identify pilot users who can validate the experience after rollout.
- Update internal Copilot adoption and training materials to include guidance on custom skills.
