Technical Description and Importance

Managing outbound B2B collaboration domains ensures that users can only share files, folders, and SharePoint sites with approved external organizations. This control helps maintain security by preventing data leakage while allowing necessary business operations. By managing these domains, organizations can align with data-sharing policies and ensure that collaboration remains within defined security boundaries. Regularly reviewing and updating these settings ensures that only relevant and necessary external entities have access.
