Unauthorized users or unfamiliar avatars are appearing in a Word document stored in a personal OneDrive account.

How to Fix Unknown Users Appearing in a Private OneDrive Word Document

Product: OneDrive and Microsoft Word
Device & OS: not provided
Scenario: Opening and viewing a personal, supposedly private Word document hosted on Microsoft OneDrive.
Observed behavior: Unknown users or guest avatars appear in the document as if they are actively viewing or editing it, even though the file is marked private and was never intentionally shared.

Before you start

Before proceeding, close the affected document to prevent any live monitoring by the unknown user, and avoid typing any sensitive information until your account security is verified.

Solution 1Recommended

Review and Revoke OneDrive File Sharing Permissions

Use this solution to ensure no accidental sharing links have been created that allow anonymous users to view your private document.

Often, unfamiliar users appear because an 'Anyone with the link' sharing option was accidentally generated. Even if you didn't email the link, its existence allows anyone who discovers it to view the file anonymously.

Open OneDrive online

Access the Manage Access panel

Right-click the document, select 'Share', and then click on 'Manage Access' (or the three-dot menu icon in the upper right corner).

Remove active links

Look for any active links under the 'Links Giving Access' section. If you see a link that says 'Anyone with the link can view/edit', click the trash can or 'X' icon next to it to permanently remove the link.

Check direct access

Review the 'Direct Access' list. If there are any unrecognized emails or users listed alongside your own, click their name and select 'Stop sharing' to revoke their permissions immediately.

Review and Revoke OneDrive File Sharing Permissions

Immediate Disconnection: Removing sharing links will instantly disconnect any unknown users currently viewing the document.

Solution 2

Secure Your Microsoft Account and Review Sign-Ins

If no sharing links exist but unknown users still appear, your Microsoft account might be compromised.

Frequently Asked Questions

Why is there an unfamiliar avatar in my private Word document?

This usually happens when an anonymous sharing link is generated for the file. Anyone who clicks that link will appear as a 'Guest' or assigned an anonymous avatar, even if you never intentionally sent the link to them.

Why doesn't my recent sign-in activity show the unauthorized user?

If a user accessed your document via a public sharing link rather than by logging into your Microsoft account, their activity won't be recorded in your account's sign-in log. The sign-in log only tracks attempts to log into the account itself.

Can unauthorized users make duplicate copies of my OneDrive file?

Yes. If an unknown user accesses your document through an edit or view link, they can use the 'Save As' feature or download the document to create their own separate duplicate copy that you cannot control.

Is it safe to post screenshots of the unknown user in support forums?

You should avoid posting unedited screenshots publicly. They may contain personal information, your email address, or parts of your private document. Always blur sensitive data or share images privately with official Microsoft Support.
