In the November 2015 or later releases of Windows 10, Enterprise State Roaming is only supported for a single account at a time. If you sign in to Windows by using a work or school Azure AD account, all data will sync via Azure AD. If you sign in to Windows by using a personal Microsoft account, all data will sync via the Microsoft account. Universal app data will roam using only the primary sign-in account on the device, and it will roam only if the app’s license is owned by the primary account. Universal app data for the apps owned by any secondary accounts won't be synced.
