Review and Manage File Access Permissions
Check the specific sharing permissions for your files and folders to ensure no broad access links were accidentally created.
OneDrive files are completely private by default. However, if a sharing link was generated with 'Anyone with the link' access, or if a broad sharing invitation was sent out, unintended users might view those specific files. Regularly reviewing the 'Manage Access' panel ensures you maintain strict control over who sees what.
Navigate to the OneDrive website and sign in with your Microsoft account credentials.
Right-click the file or folder you suspect might be compromised and select 'Manage Access' from the context menu.
Look under the 'Links Giving Access' and 'Direct Access' sections. Identify any unknown users or overly broad links.
Click the trash can icon or the 'Stop Sharing' button next to any link or user that should no longer have access to the item.
Secure Your Microsoft Account
If you suspect someone is viewing private files without any sharing links being active, your Microsoft account credentials may be compromised.
Verify File and Folder Locations
Ensure that your private files were not accidentally moved into a directory that is already shared with others.

Frequently Asked Questions
Are my OneDrive files public by default?
No. By default, all files and folders uploaded to your OneDrive are strictly private and can only be seen by you until you explicitly choose to share them.
What happens if I move a private file into a shared folder?
When you move a private file into a shared folder, it automatically inherits the permissions of that folder. Anyone who has access to the shared folder will immediately be able to view or edit the newly moved file.
Can I see exactly who viewed my shared OneDrive files?
If you are using a personal OneDrive account, you cannot typically see a list of specific individuals who viewed a file, especially if an 'Anyone with the link' option was used. However, OneDrive for Business and SharePoint users can utilize the 'Catch up' or 'Viewers' features to see specific activity.
Does sharing one file give someone access to my entire OneDrive?
No. When you share a specific file, the recipient only gains access to that exact file. They cannot browse your other files, move up to the parent folder, or see the rest of your OneDrive contents.
