Observed behavior: By default, members may have the ability to close or delete tasks they did not create, which needs to be restricted.

Solution 1Recommended

Verify Subscription and Apply Member Restrictions

Check your Microsoft 365 subscription type and configure group permissions based on Microsoft's official guidance to block unauthorized task deletions.

In Microsoft Planner, permission capabilities are closely tied to your Microsoft 365 subscription (e.g., Business, Enterprise, or Education) and the underlying Microsoft 365 Group settings.

Because Planner does not have a standalone permission matrix for task closure, you must manage these restrictions through group policies and subscription-specific admin controls.

Check your Microsoft 365 subscription

Log into the Microsoft 365 Admin Center with an administrator account to verify your current plan. Some advanced permission features are only available in specific Enterprise plans.

Access Planner as an Owner

Open Microsoft Planner and navigate to the specific plan where you want to restrict task closures to ensure you have the necessary administrative access.

Review Microsoft guidelines

Consult the official Microsoft documentation for your specific subscription tier to find the exact PowerShell commands or admin center policies required to block users from deleting tasks they did not create.

Adjust Microsoft 365 Group settings

Navigate to the Microsoft 365 Groups interface and limit the editing rights of standard members, which helps restrict unauthorized task modifications.

Default Planner Behavior: By default, any member of a plan can edit, reassign, or close any task. Advanced restrictions often require managing permissions via PowerShell or upgrading to a different Microsoft 365 tier.
