Question details

Users need to restore the read-only warning when multiple users open the same Excel file on a shared network server.

Fix Excel File Locking Not Working on a Shared Server

Product: Microsoft Excel
Device & OS: not provided
Scenario: Accessing and editing Excel spreadsheets on a shared network drive after a server migration.
Observed behavior: Excel files allow multiple users to edit the same document concurrently without displaying the standard read-only or file-in-use warning, risking data loss.

Before you start

Verify whether the file-locking issue affects all network users or just specific individuals, and ensure you have administrative access to the shared server.

Solution 1Recommended

Review Server Migration Configurations and Permissions

Check with your IT administrator to ensure the new server correctly broadcasts file-in-use statuses and maintains proper folder permissions.

When a server is migrated, changes to file-sharing protocols or folder permissions can disrupt Microsoft Office's ability to create temporary lock files. Without these lock files, Excel cannot warn subsequent users that the document is already open.

Verify shared folder permissions

Ask your server administrator to confirm that all users have the correct read, write, and modify permissions for the shared directory.

Check file-locking protocols

Ensure the server's file-sharing protocol is properly configured to support Office temporary lock files (which appear as ~$filename.xlsx).

Test with a new file

Create a new Excel workbook on the shared drive and have two users open it simultaneously to determine if the issue is file-specific or server-wide.

Review Server Migration Configurations and Permissions

Contacting Support: If server configurations appear correct, you may need to open a support case with Microsoft providing your server, Office version, and migration details.

Frequently Asked Questions

Why does Excel no longer show the read-only warning on our shared drive?

This usually happens when the network server fails to manage temporary lock files (e.g., ~$filename.xlsx) properly, often due to changed sharing protocols, restricted permissions, or caching issues introduced during a server migration.

How can I manually prevent others from editing my Excel file?

You can require a password to modify the file. Open your workbook, go to File > Save As, click 'Tools' next to the Save button, select 'General Options', and enter a password in the 'Password to modify' field.

Does Excel support multiple users editing a file on a local server?

Yes, through the legacy 'Shared Workbook' feature. However, it is prone to sync conflicts and is deprecated in newer Office versions. Cloud storage like SharePoint or OneDrive is recommended for reliable simultaneous co-authoring.
