WPN_E_NOTIFICATION_ID_MATCHED

WPN_E_NOTIFICATION_ID_MATCHED is an HRESULT used by the Windows notification platform. It means that the notification identifier used as a filter matches a notification record known to the platform.

What to check

  • Treat the result according to the API operation that returned it; it can describe a match rather than a delivery failure.
  • Verify the exact notification ID and filter semantics used by the caller.
  • Do not infer that the user saw the notification solely from an identifier match.
