Introduction

Your team finds two versions of the same drawing, a filename with an employee or computer name added, or a red X beside a folder that looked fine yesterday. One engineer has changes on a laptop, another sees an older SharePoint copy, and nobody knows which file is the master. The steps below will help you protect the work, identify the authoritative copy, correct common sync problems, and establish a safer workflow.

What You’ll Need

• A Microsoft 365 work account with access to the affected SharePoint library or OneDrive folder.
• Access to the affected Windows computer and the OneDrive desktop sync app.
• Permission to pause and resume OneDrive syncing.
• A SharePoint site owner or Microsoft 365 administrator if permissions, versioning, or library settings need to be changed.
• A protected folder outside OneDrive and SharePoint where you can temporarily store comparison copies.
• A quiet period when employees can close the affected files and stop editing them.

Do not begin by deleting duplicates or dragging entire project folders to new locations. First determine which versions contain work that must be preserved.

Step-by-Step Instructions

1. Stop New Changes and Protect Every Candidate Version

1. Ask everyone working in the affected project to save and close the files, including AutoCAD drawings, PDFs, spreadsheets, and project documents.
2. Tell the team not to rename, move, or delete anything until the conflict has been reviewed.
3. Select the blue OneDrive cloud icon in the Windows notification area, open Help & Settings or the gear icon, choose Pause syncing, and select 2 hours.
4. Create C:\File-Conflict-Review, outside all synchronized folders.
5. Copy every candidate version there and record its name, size, modified date, and last known editor. Do not assume the newest timestamp identifies the correct file.

Pausing sync is temporary. It prevents more changes from entering the queue while you compare files, but it does not repair the underlying problem.

2. Identify the Authoritative Cloud Location

1. Select the OneDrive cloud icon and choose View Online, or open the correct SharePoint site in a browser.
2. Navigate to the document library and project folder where the master file should live. Confirm whether it is a team library, personal OneDrive, Teams-connected library, or another platform.
3. Select the file, open More options, and choose Version history.
4. Review the editor, date, time, and size of each version. Download any version that may contain unique work into C:\File-Conflict-Review.
5. Compare the protected copies. For DWGs, have the project lead or CAD manager determine which geometry and revisions must be retained.
6. Do not select Restore or return a chosen file to the project folder until the sync problem is resolved.

Microsoft supports Version History for file types including PDFs and CAD files, although retention depends on the organization’s configuration.

3. Read the OneDrive Status Before Changing Anything Else

1. Select the blue OneDrive cloud icon in the Windows notification area.
2. Review the activity list for Can’t sync, Sync pending, or Processing changes.
3. In File Explorer, check the affected folder’s status column. A red circle with a white X indicates a sync failure; circular arrows indicate syncing is in progress.
4. Confirm the file appears in the browser before assuming it uploaded successfully.
5. Resume syncing only after protecting candidate versions and correcting obvious filename or path problems.

The browser confirms what reached Microsoft 365, but it cannot show changes still trapped on an employee’s computer.

4. Correct Invalid Names and Excessively Long Paths

1. Look for filenames or folder names containing these restricted characters: " * : < > ? / \ |.
2. Remove leading or trailing spaces and avoid reserved names such as .lock, CON, PRN, AUX, NUL, desktop.ini, and names beginning with ~$.
3. Shorten deeply nested project structures while retaining meaningful project, phase, and discipline labels.
4. In File Explorer, select the address bar to inspect the complete path. If Windows cannot rename the item, shorten it in the SharePoint browser.
5. Resume syncing and confirm the error clears in the OneDrive activity window.

Project numbers, client names, phases, disciplines, and revisions can quickly create excessively long engineering paths.

5. Standardize How Each Library Connects to File Explorer

1. Decide whether the firm will use Add shortcut to OneDrive or the SharePoint Sync button for a particular library or folder.
2. Do not have the same employee connect to the same project content through both methods. This can create confusing duplicate paths and make employees unsure which folder they are editing.
3. For a shortcut, open the SharePoint library, select the folder, and choose Add shortcut to OneDrive. Microsoft currently recommends shortcuts when available.
4. For device-specific synchronization, open the library, select Sync, approve the request to open OneDrive, and finish signing in.
5. Confirm the folder appears under the correct organization in File Explorer and document the approved path. Do not remove an existing connection until all pending changes are verified.

The main goal is one consistent, documented path for each project.

6. Make Active Project Files Available Locally When Appropriate

1. In File Explorer, locate the active project folder.
2. Review the status icons. A blue cloud means the item is online-only, while a solid green circle with a white check means it is set to remain available locally.
3. For files that must remain local, right-click the folder and select Always keep on this device. Wait for the download to finish before opening engineering files.
4. Use Free up space only for folders that can remain online-only, and confirm sufficient disk space before pinning a large project.

Files On-Demand helps conserve disk space, but it does not prevent two people from editing the same non-coauthoring file. Local availability and file-locking are separate issues.

7. Establish Specific Rules for DWG Files and External References

1. Do not allow two people to edit the same DWG simultaneously through an ordinary SharePoint-synchronized folder.
2. Assign a clear owner to each active drawing, sheet, or discipline file and require that person to close it before another employee takes over.
3. Keep related DWGs, xrefs, images, and support files in a consistent project structure.
4. Use relative xref paths where the CAD standard permits them, so references do not depend on one employee’s username or drive letter.
5. Wait for synchronization to complete before another employee opens the file.
6. Use Version History for recovery, not as a substitute for file locking. For simultaneous CAD collaboration, evaluate Autodesk Docs with Desktop Connector or another tested engineering platform.

Autodesk warns that SharePoint may not provide the normal read-only alert when multiple people open the same DWG.

8. Reset OneDrive Only After the File-Level Problems Are Protected

1. Close all files stored in OneDrive or synchronized SharePoint libraries.
2. Confirm important files are visible online and preserve unsynced local copies outside OneDrive.
3. Press Windows key + R, enter %localappdata%\Microsoft\OneDrive\onedrive.exe /reset, and select OK.
4. If Windows cannot find it, try C:\Program Files\Microsoft OneDrive\onedrive.exe /reset or C:\Program Files (x86)\Microsoft OneDrive\onedrive.exe /reset.
5. Start OneDrive from the Start menu if it does not reopen.
6. Confirm the correct work account reconnects and allow synchronization to finish before opening project files.

Resetting does not delete cloud data, but it resets connections and triggers a full sync. Do not perform it across multiple workstations during a deadline.

9. Test the Workflow Before Releasing the Project Back to the Team

1. Create a noncritical test folder inside the approved project location.
2. Have one user edit a test file, close it, and wait for synchronization to complete.
3. Confirm the version appears in the SharePoint browser and Version History before a second user opens it.
4. Test a small DWG with an xref in the planned folder structure and confirm the reference resolves on both computers.
5. Verify permissions, then document the master location, connection method, filename rules, DWG ownership, and handoff procedure.

When to Call a Professional

Call an IT professional when conflicts affect several users or project libraries, employees see different folder trees, sync repeatedly stalls, permissions are inconsistent, or nobody can confidently identify the authoritative copy. You should also get help before migrating active projects, changing library architecture, resetting many workstations, or relying on SharePoint for a multi-user CAD workflow.

Incorrectly removing shortcuts, stopping synchronization, restoring the wrong version, or moving project folders can create more duplicates, break xrefs, or delete cloud-connected files from locations used by the rest of the team. An MSP or Microsoft 365 specialist should review the SharePoint structure, permissions, OneDrive policies, endpoint configuration, backup strategy, and engineering application requirements together.

FAQ

Why does OneDrive create a second copy with a person’s or computer’s name?

That usually means OneDrive could not safely combine two sets of changes. It preserves another copy rather than silently overwriting one person’s work. Compare both versions before renaming or deleting either file.

Can engineering firms safely store AutoCAD files in SharePoint or OneDrive?

They can be useful for controlled storage, sharing, and version history. Active DWG collaboration requires more care because ordinary SharePoint synchronization may not provide the file-lock behavior users expect from a traditional file server. Do not assume that a workflow suitable for Word or Excel is automatically suitable for AutoCAD.

Which copy is the master, the one in File Explorer or the one in SharePoint?

When synchronization is healthy, they represent the same cloud item. When synchronization has failed, the local computer may contain changes that never reached SharePoint. Check the browser copy, sync status, Version History, and protected local copies before deciding which version is authoritative.

Should we use Sync or Add shortcut to OneDrive?

Microsoft currently recommends Add shortcut to OneDrive when available because the shortcut follows the user across devices. The Sync button can still be appropriate for device-specific needs. The more important rule is to standardize one method for each project location and avoid connecting the same content twice.

Does resetting OneDrive delete our files?

Microsoft states that a reset does not delete the files or cloud data. It does reset sync connections and causes OneDrive to perform a full synchronization. Protect unsynced local work first, and involve IT if several libraries, accounts, or users are affected.
