How to Fix a Read-Only SharePoint User Editing a Word Document

WPS Content Manager Oct 9, 2026 868 views

Question details

An external user with only read-only permissions in a SharePoint document library is unexpectedly able to edit and save a Microsoft Word document using the desktop application.

Why Can a Read-Only SharePoint User Edit a Word Document?

Product: Microsoft Word and SharePoint
Device & OS: not provided
Scenario: An external user opens a shared SharePoint document expected to have read-only rights, but finds they have full editing capabilities when opening the file in the local desktop application.
Observed behavior: The Word desktop app allows the user to modify and save changes to the document, bypassing the read-only restriction configured in the SharePoint library.

Before you start

Confirm the exact permission level assigned to the external user's account in the SharePoint document library settings before troubleshooting the desktop application.

Solution 1Recommended

Verify the Signed-In Account in the Word Desktop App

Use this solution to check if the Word desktop application is using cached credentials from an internal account with edit permissions rather than the external user's account.

The most common reason for this permission discrepancy is that the Office desktop application is signed in with a different account than the one used to access the SharePoint link in the web browser. If an internal account with full editing rights is active in the desktop app, Word will use those elevated permissions.

Open the document information

Have the user open the affected document in the Word desktop app and click on 'File' in the top-left corner, then select 'Info'.

Compare the document path

Click 'Copy Path' under the document name and paste it into a text editor. Compare this path with the shared SharePoint location to ensure they are working on the live server file.

Check the signed-in user account

Navigate to 'File' > 'Account' (or 'Office Account'). Look at the 'User Information' section to see which email address is currently signed in to the application.

Switch to the correct account

If the app is signed in with an internal or highly-privileged account, click 'Sign out'. Then, have the external user sign back in with their own designated external credentials to enforce the proper read-only limits.

Permissions Restored: Once the desktop application is authenticated exclusively with the external user's account, the document will correctly lock into read-only mode.

Frequently Asked Questions

Can SharePoint read-only permissions be overridden by Word desktop app settings?

SharePoint permissions are strictly enforced on the server side. However, if the Word desktop app is signed into an account with edit permissions, it will utilize those higher permissions instead of the external user's read-only web link.

Why doesn't the web version of Word have this editing issue?

The web version of Word uses the session credentials of the currently logged-in web browser user (the external read-only account). The desktop app operates independently and may retain cached credentials of a different, internal account.

How do I force a Word document to open in read-only mode for everyone?

In Microsoft Word, you can go to File > Info > Protect Document and select 'Always Open Read-Only', or apply 'Restrict Editing' with a password to prevent unauthorized changes regardless of SharePoint library configurations.
