Question details

The user needs to know if Microsoft Project linking structures, such as master projects and resource pools, are supported and function correctly when stored in SharePoint or OneDrive.

Are Microsoft Project Links Supported in SharePoint and OneDrive?

Product: Microsoft Project, SharePoint, OneDrive
Device & OS: not provided
Scenario: Storing and collaborating on linked Microsoft Project files (including master projects, subprojects, and resource pools) using Microsoft cloud storage platforms.
Observed behavior: Microsoft Project linking structures become corrupted or fail to function properly because they are not supported for use on SharePoint or OneDrive.

Before you start

Before restructuring your Microsoft Project files or moving them to a new location, ensure you have a complete local backup of all master projects, subprojects, and resource pools to prevent data corruption.

Solution 1Recommended

Migrate Linked Project Files to a Network Shared Server

Since SharePoint and OneDrive do not support Microsoft Project linking structures, storing your files on a traditional network shared server is the recommended method to maintain link integrity.

Microsoft officially does not support the use of SharePoint or OneDrive for Microsoft Project master projects, subprojects, resource pools, and linked sharer files. The cloud sync engines conflict with the local file paths required by MS Project.

Map a network drive

Open File Explorer on your computer, select 'This PC', click 'Map network drive', and connect to a local shared server that all collaborators can access using the exact same drive letter.

Transfer project files

Copy and paste your master projects, subprojects, and resource pools from the unsupported SharePoint or OneDrive folders into the newly mapped network drive.

Re-establish file links

Open the master project in Microsoft Project from the network drive. Go to the 'Project' tab, use the 'Subproject' button to re-insert and re-link your subprojects and resource pools using the new, stable network drive paths.

Migrate Linked Project Files to a Network Shared Server

Maintain Regular Backups: Even on a supported shared server, complex Microsoft Project linking structures can occasionally become corrupted. Always maintain reliable backups and verify that this setup meets your team's collaboration needs.

Frequently Asked Questions

Why are Microsoft Project links not supported in SharePoint?

SharePoint and OneDrive use URL-based file paths and web synchronization mechanisms that conflict with Microsoft Project's local, file-based linking engine. This mismatch prevents proper path resolution, often leading to broken links or permanent file corruption.

Will my personal OneDrive work for linked Microsoft Project files?

Although some users report temporary success using personal OneDrive as a local sync folder, it is strictly not supported by Microsoft. Complex linking structures will eventually face sync conflicts and data corruption when processed by the OneDrive sync client.

How can I safely share project plans in SharePoint?

To safely store Microsoft Project files in SharePoint or OneDrive, you must consolidate your work into standalone project files. Do not use external links to subprojects or shared resource pools if you plan to host the files on a cloud service.
