Importantly, this prompt does not combine or transfer files between personal and corporate accounts. Users must take deliberate action to move or save files between accounts, and Microsoft blocks the move of known folders to personal OneDrive accounts from domain joined devices by default. Additionally, data protection features such as sensitivity labels and data loss prevention (DLP) policies continue to apply.
