Question details

The user wants to know why changes made to shared OneDrive files are attributed to "Guest collaborator" and how to display the actual names of the contributors.

Product: Microsoft OneDrive
Device & OS: not provided
Scenario: Collaborating on shared documents using OneDrive links.
Observed behavior: Document edits are recorded under the generic name "Guest collaborator" instead of an identifiable person's name when using the "Anyone with the link" sharing option.

Before you start

Ensure you have the correct permissions to modify the sharing settings of the OneDrive file, and notify your collaborators that they will need to sign in with their Microsoft or organizational accounts.

Solution 1Recommended

Change Sharing Link to Specific People

Replace the anonymous sharing link with a secure link that requires users to authenticate, ensuring their names appear in the document history.

When a OneDrive file is shared using the 'Anyone with the link' option, users can edit the file without signing in. Because Microsoft cannot verify the identity of an unauthenticated user, all changes are attributed to a 'Guest collaborator'. To fix this, you must restrict access to specific invited users.

Open OneDrive Sharing Settings

Navigate to your OneDrive folder, locate the document you want to share, right-click the file, and select the 'Share' option.

Modify the Link Settings

In the sharing dialog box, click on the current sharing configuration (usually displaying 'Anyone with the link can edit') to open the detailed Link settings menu.

Select Specific People

Choose 'Specific people' from the available sharing options. Ensure the 'Allow editing' checkbox is selected if you want them to make changes, then click 'Apply'.

Invite Collaborators

Enter the email addresses of the people you want to collaborate with and click 'Send'. When they access the file, they will be prompted to authenticate, allowing their actual names to be recorded in the document history.

Authentication Requirements: Each invited collaborator must authenticate with a Microsoft account or an approved organizational identity. Sharing behavior and available options may differ between personal and business Microsoft 365 accounts.

Frequently Asked Questions

Can I force OneDrive to ask for a guest name without requiring them to sign in?

No, Microsoft OneDrive currently does not have a feature that allows unauthenticated guests to manually enter their names. To track names, they must be invited via the 'Specific people' option and sign in with a verified account.

Why do some verification emails fail to send when using the Specific people option?

Verification emails can sometimes be blocked by institutional or corporate spam filters. If this happens, ask the recipient to check their junk or spam folder, or contact their IT administrator to whitelist Microsoft sharing notifications.

Does the Guest contributor issue apply to both personal and business OneDrive accounts?

Yes, the 'Anyone with the link' setting acts similarly across personal and business accounts by anonymizing users as Guest collaborators. However, organizational IT policies might restrict anonymous sharing entirely on business accounts.
