The Shared with Everyone folder that you may see as a part of your default OneDrive for Business document folders is a bit confusing. What you put in that folder is indeed accessible to everyone, but each user’s folder is unique. So the contents in your folder are only in yours and another user has different content they have placed there. To see a file in another user’s folder, the file would need to be returned in your search results or you would need to receive a direct link from the file owner. As a result, you may want to consider your SharePoint Online Team Site for any files that your whole team needs easy access to rather than your OneDrive.
