Question details

Users need to know how to properly update files attached to Planner tasks, as edits made to the original OneDrive files are not reflecting in Planner.

How to Fix Microsoft Planner Not Updating OneDrive Attachments

Product: Microsoft Planner
Device & OS: not provided
Scenario: A user attaches a file from their personal OneDrive to a Microsoft Planner task and later edits the original file, expecting the changes to sync to the task.
Observed behavior: The file attached to the Planner task does not update when the original file in OneDrive is modified, resulting in outdated task attachments.

Before you start

Ensure you have editing permissions for the Microsoft 365 Group and its connected SharePoint site, as Planner attachments are stored centrally in SharePoint rather than your personal OneDrive.

Solution 1Recommended

Edit the Document Directly in the Associated SharePoint Library

To keep task attachments current, you must edit the file copy that is stored in the SharePoint library associated with your Microsoft Planner plan.

When you attach a file from OneDrive to a Planner task, Planner uploads a separate copy of that file to the SharePoint document library associated with the plan's Microsoft 365 group. Because they are now two distinct files, any subsequent edits to the original OneDrive file will not push to Planner.

Open the Planner task

Navigate to Microsoft Planner, open your specific plan, and click on the task card containing the attachment you want to update.

Access the SharePoint hosted file

Click directly on the file attachment within the task card. This will open the document in Office for the Web, hosted securely on your team's SharePoint site.

Make your edits

Edit the document as needed. Changes are automatically saved to the SharePoint document library and will be instantly visible to any team member viewing the Planner task attachment.

Edit the Document Directly in the Associated SharePoint Library

SharePoint integration is required: SharePoint cannot be bypassed in this process. Planner relies on SharePoint's team file storage architecture to ensure all Microsoft 365 group members have consistent access to task attachments.

Frequently Asked Questions

Why don't my OneDrive updates show up in Microsoft Planner?

When you attach a file from OneDrive to Planner, a copy is uploaded to the team's SharePoint document library. Updating the original file in your personal OneDrive does not update the separate copy now stored in SharePoint.

Can I use Microsoft Planner without SharePoint?

No, SharePoint is integral to Microsoft Planner. Every plan is connected to a Microsoft 365 Group, which strictly uses a SharePoint site as its backend for storing and managing all team files and attachments.

How can I retrieve Planner attachments using Power Automate?

You can create a flow using the 'Get file content' action in Power Automate. Ensure you point the path to the specific SharePoint Document Library associated with your Planner's Microsoft 365 group, rather than a generic shared documents path.
