I have invited my daughter to my Microsoft 365 family subscription.

Although she is supposed to have her own 1TB One Drive space, she can view my files on her One Drive file explorer.

How can I stop her from sharing my One Drive space and do not have access to my files?

    Hi, @Kelly Vichou

    Sharing a Microsoft 365 Family subscription does not automatically give family members access to each other's OneDrive files. Each member has their own Microsoft account and separate 1 TB OneDrive storage.

    To help narrow this down:

    1. Is your daughter signed in to OneDrive using her own Microsoft account or the same account as yours?
    2. Can she see all your files or only specific folders?
    3. Are your files appearing under "My files" or the "Shared" section in her OneDrive?

    In the meantime, check whether you have explicitly shared any folders or files with her. You can review and revoke access through OneDrive's "Manage access" option.

    This happens when the same Microsoft account is being used in OneDrive or Office on multiple PCs. A Microsoft 365 Family subscription gives each person separate storage only when each person signs in with their own Microsoft account. It does not merge storage by subscription, but using the same sign-in can make one person’s OneDrive files appear on another device.

    To stop access to the files:

    1. Confirm the subscription share is set up correctly.
      • The subscription owner should go to the Microsoft account services page and open Sharing.
      • Verify the daughter is listed as someone the subscription is shared with.
    2. On the daughter’s PC, sign out of the wrong OneDrive account.
      • Select the OneDrive cloud icon.
      • Go to Help & Settings > Settings > Account.
      • Check which Microsoft account is signed in.
      • If it is the parent’s account, select Unlink this PC.
      • Then sign in again with the daughter’s own Microsoft account, the same one that accepted the family sharing invitation.
    3. If Office apps also show the wrong subscription, sign out there too.
      • Open Word or Excel.
      • Go to File > Account.
      • Sign out of the old account.
      • Sign back in with the daughter’s Microsoft account that has the shared Microsoft 365 Family benefit.
    4. If files were shared directly from OneDrive, remove that sharing.
      • In OneDrive, select the file or folder.
      • Select Information in the upper-right corner.
      • Open Manage access.
      • Remove the sharing link with X or remove access for specific people.
    5. If the parent wants to stop sharing Microsoft 365 benefits entirely, stop sharing the subscription.
      • Go to the Microsoft account services page, choose Sharing, find the person, and select Stop sharing.
      • This removes subscription benefits such as extra OneDrive storage and desktop apps.

    Expected result: after the daughter’s PC is signed in to OneDrive with her own Microsoft account, her File Explorer should show only her own OneDrive storage unless files or folders were explicitly shared.
