How to identify anonymous file shares on O365

Anonymous sharing of files in Office 365, specifically through SharePoint or Onedrive, typically involves providing access to files or folders to individuals who do not have an Office 365 account or are not part of the organization. While anonymous sharing is a valuable feature, it's important to use it wisely and consider security implications. Organizations should carefully configure sharing settings, monitor access, and, if needed, set expiration dates on shared links to ensure that sensitive information remains protected.
