Question details

The user needs to link subprojects to a master project using Microsoft Project, but the linking functionality is failing when the files are stored on SharePoint.

How to Fix Microsoft Project Subprojects Linking on SharePoint

Product: Microsoft Project, SharePoint
Device & OS: not provided
Scenario: Attempting to create a master project with linked subprojects and shared resource pools in a cloud-based storage environment like SharePoint or OneDrive.
Observed behavior: Project linking does not work because SharePoint and OneDrive are not supported storage locations for linked Microsoft Project files.

Before you start

Verify that your organization has an accessible local network drive and that all project contributors have proper read and write permissions to that drive.

Solution 1Recommended

Migrate Master Project and Subprojects to a Shared Network Folder

To maintain proper file links between master projects and subprojects, you must move all associated files from SharePoint to a standard shared network folder.

Microsoft Project's architecture requires fixed file paths for linked master projects, shared resource pools, and subprojects. Cloud synchronization systems like SharePoint and OneDrive dynamically generate web-based paths that break these links.

Identify a Local Network Drive

Find or request a mapped network drive (e.g., a Z: drive) on your company's local network that all project team members can access.

Transfer Project Files

Download your master project, all subprojects, and any shared resource pool files from SharePoint and copy them directly into the new shared network folder.

Re-establish Links via Desktop App

Open the master project using the desktop Microsoft Project app. Re-insert or re-link the subprojects using the new network folder paths so the system can establish a stable connection.

Migrate Master Project and Subprojects to a Shared Network Folder

Desktop Application Required: Make sure all users open the master project and subprojects using the Microsoft Project desktop application rather than a web interface to ensure links remain intact.

Solution 2

Consolidate into a Single Project File on SharePoint

If your organization only uses SharePoint and cannot provide a network folder, you must abandon the linked subproject structure.

Frequently Asked Questions

Why does Microsoft Project linking fail on SharePoint and OneDrive?

SharePoint and OneDrive use dynamic web-based URLs for file synchronization. Microsoft Project's file-linking feature requires static local or mapped network file paths to maintain the complex relationships between master projects and subprojects.

Is there any workaround to use SharePoint for a master project?

There is no direct workaround to maintain live links. If you must use SharePoint, your only option is to consolidate all tasks and resources into a single, unlinked Microsoft Project file.

Does syncing a SharePoint library to my local computer fix the linking issue?

No. Even if you use the OneDrive sync client to sync a SharePoint folder to your local PC, the underlying architecture still treats it as a cloud location, and Microsoft Project linking will remain unsupported and unstable.
