Users appearing as 'Guest Contributor' instead of their actual name when co-authoring a shared document.

How to Fix SharePoint Displaying User as Guest Contributor

Product: Microsoft SharePoint / Word
Device & OS: not provided
Scenario: Co-authoring and collaborating on a shared document in real-time.
Observed behavior: The document displays another editor as a 'Guest Contributor' rather than showing their specific Microsoft account name while the document is being edited.

Before you start

Ensure you have the necessary file permissions (usually Owner or Editor level) to modify the sharing settings of the affected SharePoint document.

Solution 1Recommended

Update Link Sharing Settings to Require Authentication

By changing the document's sharing permissions from an 'Anyone' link to a targeted user link, SharePoint will require the user to sign in, correctly displaying their actual name.

When a document is shared using an 'Anyone with the link' option, the system does not require the recipient to authenticate their identity. Consequently, SharePoint and Word default to labeling these anonymous editors as Guest Contributors.

To resolve this behavior, you must revoke the anonymous link and generate a new, secure link directed at specific users.

Access Manage Access

Open your SharePoint document library, hover over the affected file, click the ellipsis (...) icon, and select 'Manage Access'.

Remove the Anyone Link

Locate the active link that states 'Anyone with the link can edit'. Click the trash can icon or 'Stop sharing' next to it to delete this anonymous link.

Create a Specific People Link

Click the 'Share' button again, click the gear icon to open Link settings, and select either 'Specific people' or 'People in your organization'.

Resend the Invitation

Enter the email addresses of your collaborators and click 'Send'. When they access the file using this new link and log in, their true names will be displayed during co-authoring.

Update Link Sharing Settings to Require Authentication

Verification: Once the collaborator joins the document via the new link, look at the top right corner of the Word interface; their account avatar and name should now appear correctly.

Frequently Asked Questions

Why do internal team members appear as Guest Contributors?

Internal users will still show as Guest Contributors if they open an 'Anyone with the link' URL while they are not signed into their Microsoft 365 account in that specific browser session.

Can I track who made changes if they were a Guest Contributor?

No, changes made by users acting as Guest Contributors are logged anonymously. To maintain an accurate audit trail, always share documents using 'Specific people' or 'People in your organization' links.

Does this happen in both the desktop app and the web version?

Yes, this can happen in both Word for the Web and the desktop Word application if the user accesses the document via an anonymous sharing link without completing the authentication process.
