How to Manage Microsoft Project Files and Version Updates in OneDrive
Question details
Users need to know the best practices for storing Microsoft Project files in OneDrive, organizing master and subproject structures, and tracking schedule versions safely.

- Product
- Microsoft Project
- Device & OS
- not provided
- Scenario
- Collaborating on and managing version history of complex Microsoft Project schedules involving master files and multiple subprojects.
- Observed behavior
- Users require a reliable method to store .mpp files in OneDrive without file corruption, ensure version retention during periodic reviews, and handle multi-user updates correctly.
Ensure you have the OneDrive desktop client installed and fully synced to your local drive before opening .mpp files, as Microsoft Project does not natively support AutoSave.
Store and Edit Project Files in a Local OneDrive Folder
Use the local synced OneDrive folder to store and open your Microsoft Project files to prevent conflicts and ensure stable saving.
Microsoft Project desktop application functions best with local files. Opening them directly from a cloud URL can cause synchronization errors. Always use the local OneDrive sync client.
Ensure your OneDrive client is running and the target folder is set to synchronize with your local hard drive.
Navigate to the local OneDrive folder using Windows File Explorer and double-click the .mpp file to open it in the Microsoft Project desktop application.
Because Project does not support AutoSave, manually save your progress frequently. Wait for the OneDrive icon to display a green checkmark indicating the file has successfully synced to the cloud.

Manage Master and Subproject Version History
Keep related project files together and use a strict folder-copying method to retain historical versions of your schedules.
Upgrade for Multi-User Collaboration
Transition to enterprise project management platforms if your team requires simultaneous co-authoring on shared schedules.
Manage Project Plans and Reports with WPS Office
While managing .mpp files requires specialized software, you can handle daily project documentation, tracking, and Gantt charts seamlessly using WPS Office. It provides a lightweight, free alternative for comprehensive project management tasks.
- 1. Install WPS Office: Download and install the free WPS Office suite on your computer or mobile device.
- 2. Access Project Templates: Open WPS Spreadsheet, go to the template library, and search for 'Project Management' or 'Gantt Chart'.
- 3. Collaborate in Real-Time: Input your project tasks and save the file to WPS Cloud to allow simultaneous co-authoring with your team.

Frequently Asked Questions
Does Microsoft Project support AutoSave when files are stored in OneDrive?
No, Microsoft Project does not support the AutoSave feature, even when files are located in a synced OneDrive folder. You must manually save your changes to ensure your work is preserved and synchronized to the cloud.
Can multiple users edit an .mpp file in OneDrive at the same time?
Simultaneous co-authoring is not supported for Microsoft Project files in OneDrive. If multiple users attempt to edit the file at once, it will create conflicting copies. For real-time multi-user collaboration, Project Online or Project Server is required.
What is the safest way to back up master and subproject versions?
Because master projects rely on exact file paths to their subprojects, the safest backup method is to copy the entire folder containing both the master and all related subprojects. Name the new folder with the version date to keep the file relationships intact.
