WPN_E_OUT_OF_SESSION
WPN_E_OUT_OF_SESSION is an HRESULT used by the Windows notification platform. It means that the platform has no available presentation-layer session for the requested notification operation.
What to check for WPN_E_OUT_OF_SESSION
- Reduce unnecessary notification churn and ensure notification objects are released when no longer needed.
- Check for application behavior that creates many concurrent notification operations.
- Treat the condition as a resource-pressure signal and retry only after capacity can recover.
Diagnostic discriminator: Check whether an eligible interactive/presentation session exists at the time of the call. This result is session availability, not a malformed notification or network response.
