Remarks
This method enables UI Automation clients to get IUIAutomationElement interfaces for accessible objects implemented by a Microsoft Active Accessibility server.
This method may fail if the server implements UI Automation provider interfaces alongside Microsoft Active Accessibility support.
The method returns E_INVALIDARG if the underlying implementation of the Microsoft UI Automation element is not a native Microsoft Active Accessibility server; that is, if a client attempts to retrieve the IAccessible interface for an element originally supported by a proxy object from Oleacc.dll, or by the UIA-to-MSAA Bridge.
