Question details

A specific Microsoft Planner plan embedded within a SharePoint team site is failing to update or synchronize.

Fix Microsoft Planner Plan Not Syncing with SharePoint

Product: Microsoft Planner and SharePoint
Device & OS: not provided
Scenario: Embedding and viewing a Planner plan within a SharePoint team site.
Observed behavior: The embedded plan does not sync or update, even after comparing settings with working plans and attempting to remove and re-add the plan to the SharePoint site.

Before you start

Ensure you have Microsoft 365 administrator privileges if you need to open a support ticket, and verify your network connection is stable before troubleshooting.

Solution 1Recommended

Contact Microsoft Support for Backend Investigation

If removing and re-adding the plan does not resolve the issue, the problem likely requires backend data investigation and service log collection by Microsoft Support.

When a sync failure is isolated to a single plan and basic troubleshooting steps fail, it often indicates a backend data anomaly or corruption specific to that plan's unique ID.

Log into the Admin Center

Navigate to Support

On the left navigation pane, click on 'Show all' if necessary, then select 'Support' followed by 'Help & support'.

Open a Support Request

Briefly describe the sync issue with the specific Planner plan and SharePoint site, then proceed to contact support to initiate backend investigation.

Contact Microsoft Support for Backend Investigation

Admin Rights Required: Only Microsoft 365 administrators can open official support tickets in the admin center. If you are a standard user, please contact your IT department.

Solution 2

Check the Service Health Dashboard

Verify if there is an ongoing Microsoft 365 outage affecting Planner or SharePoint services globally or regionally.

Frequently Asked Questions

Why is only one Planner plan failing to sync on SharePoint?

This usually points to a backend data corruption or sync anomaly specific to that plan's ID, rather than a global configuration error. Microsoft Support needs to investigate the service logs for that specific plan.

Can I embed a different Planner plan as a workaround?

Yes. If the issue is isolated to a single plan, creating a new plan and migrating your tasks, or embedding a different existing working plan via the Planner web part, can serve as an effective temporary workaround.

Do I need admin rights to fix SharePoint sync issues?

While site owners can attempt basic troubleshooting like removing and re-adding the Planner web part, escalating the issue to Microsoft Support for backend log collection requires Microsoft 365 administrator privileges.
