How to Fix Word Co-Authoring When Editing Is Locked
Question details
Users cannot collaborate in real time on a shared Word document stored in OneDrive because the application incorrectly reports that editing is locked by the owner.

- Product
- Microsoft Word, OneDrive
- Device & OS
- not provided
- Scenario
- Attempting to co-author a shared Word document with other users via OneDrive or SharePoint.
- Observed behavior
- The document displays an 'editing is locked by the owner' prompt, preventing users from seeing edits in real time even though the file is accessible.
Verify that your internet connection is stable and ensure all collaborating users are signed in to the correct Microsoft accounts associated with the shared OneDrive link.
Upgrade the Document to the Supported DOCX Format
Convert older .doc files to the modern .docx format, as real-time co-authoring is only supported in newer file types.
Real-time co-authoring features in Microsoft Office require the document to be in a modern format (DOCX). If a file was created in an older version of Word (DOC), it will restrict multiple users from editing the file simultaneously and cause file lock errors.
Launch Microsoft Word and open the shared document that is currently displaying the locked error.
Click on the 'File' tab in the top-left corner of the ribbon, then select 'Save As' from the left-hand menu.
Choose your OneDrive or SharePoint location. In the 'Save as type' dropdown menu, select 'Word Document (*.docx)' and click 'Save'.
Delete or archive the old .doc file and share the newly created .docx file with your collaborators to enable real-time co-authoring.

Force Release the Document Lock via OneDrive
Resolve persistent server locks by ensuring the document owner completely closes their session and manages access in OneDrive.

Frequently Asked Questions
Why does Word say editing is locked by another user when no one is editing?
This typically occurs if Microsoft Word crashed or did not close properly during a previous session, leaving a temporary lock file on the server. It can also happen if the file is open on another device owned by the same user.
Does real-time co-authoring work with older .doc files?
No, real-time co-authoring strictly requires the modern .docx file format. Older .doc files must be converted using the 'Save As' function before multiple users can collaborate on them simultaneously.
Can I co-author a Word document stored on my local computer?
No, real-time collaboration requires the document to be saved in a supported cloud storage location, such as OneDrive or SharePoint, so that edits can be synced across the network.
How do I force Word to unlock a file?
You can force unlock a file by asking the document owner to close all instances of the file. Alternatively, saving a local copy of the file under a new name and uploading it to OneDrive as a fresh document will bypass the lock.
