Question details

The user is seeing unfamiliar guest viewers in their Word documents stored on OneDrive, despite not recalling sharing the files.

Product: Microsoft OneDrive
Device & OS: not provided
Scenario: Monitoring document security and investigating unrecognized viewer activity in a cloud-stored file.
Observed behavior: Unknown or random guest names appear as active viewers in a OneDrive Word document.

Before you start

Before modifying permissions, verify with your IT administrator if your organization has recently granted document access to third-party services or system integrations, as these can sometimes manifest as unknown guest activity.

Solution 1Recommended

Review and Remove 'Anyone with the link' URLs

Check your document's sharing settings to ensure open access links have not been accidentally created or forwarded by others.

When a document is shared using an 'anyone-with-the-link' setting, anyone who clicks the link can access the file. If these users are not logged into a Microsoft account, they will appear as anonymous guests.

Access Document Settings

Open OneDrive in your web browser and locate the affected Word document.

Open Manage Access

Right-click the file and select 'Manage Access', or click the three vertical dots next to the file name and choose 'Manage Access'.

Locate Active Links

Look for the 'Links giving access' section to see if an 'Anyone with the link can view/edit' URL exists.

Delete Unwanted Links

Click the trash can icon or 'Remove link' button next to any unrecognized or unneeded sharing links to revoke public access immediately.

Access Revoked: Removing the link will instantly disconnect any anonymous guests currently viewing the document.

Solution 2

Verify Organization and Third-Party Permissions

Confirm if the guest viewers are actually authorized third-party service providers or internal organizational accounts.

Frequently Asked Questions

Why do random animal or guest names appear in my Word document?

If you or someone else shared the file using an 'Anyone with the link' setting, Microsoft assigns anonymous viewers random names (such as 'Guest Contributor') when they open the document without being logged into a Microsoft account.

Can someone access my OneDrive files if I didn't directly share them?

Yes, this can happen if your file is placed inside a folder that is already shared, if it inherits permissions from an organizational SharePoint site, or if your IT department has granted access to external service providers.

How can I see exactly who has access to my OneDrive file?

Right-click the file in OneDrive, select 'Manage Access', and click 'Advanced' or 'Direct Access' to view a comprehensive list of every user, group, and link that has permission to view or edit the document.

Will deleting a sharing link kick out current viewers?

Yes. Once you remove the active sharing link from the 'Manage Access' menu, anyone currently viewing the document via that link will immediately lose access and be prompted to request permission.
