This new feature prompts users who are signed intointroduces a prompt only when a personal Microsoft account is already signed in on a Windows device and actively using their corporate OneDrivethe device, encouraging users to also sign intoin to the OneDrive app with theirthat account. This update does not “sync” personal account. Once signed in, users canfiles with corporate accounts or vice versa. It simply allows access both their personal and corporateto separate OneDrive accounts on the same device—device without merging content. The prompt is enabled by defaultcontent – similar to checking both work and only appears if a personal account isemails on one device without combining inboxes. Administrators who have already in use on the device. Organizations that have previously restricted personal account usage withaccounts on corporate devices can continue to manage this as before.

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 DisablePersonalSync policymove 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.

Devices in regions where the Digital Markets Act is applicable will not see thethis prompt. Administrators can also suppress it using the DisableNewAccountDetection policy.
