Summary

The Project Manager agent in Planner will preview a feature using encrypted SharePoint files for improved task creation and execution. New Plans enable this by default; existing Plans require manual activation. Tasks from encrypted files become unencrypted for export. Rollout starts late July 2025, completing late August 2025.

Body (from Message Center)

We're introducing a new capability in Preview for the Project Manager agent in Planner. This enhancement enables the agent to utilize encrypted files from the SharePoint site associated with the Microsoft 365 group of the Plan for grounding. By leveraging these files, the agent can improve task creation from goals and execution of assigned tasks, ensuring more accurate and secure project management automation.

When this will happen

Public Preview rollout begins: Late July 2025
Expected completion: Late August 2025

How this affects your organization

New Plans with Project Manager agent:
- SharePoint Site grounding is enabled by default during Plan creation.
- Admins and users can disable this feature during or after Plan creation.
Existing Plans with Project Manager agent or Premium Plans:
- SharePoint Site grounding is disabled by default.
- Admins can enable it manually within the Plan settings.
Task and file behavior:
- When encrypted SharePoint files are used for grounding, the resulting tasks and files are unencrypted and can be exported, printed, and downloaded.
