The MAPI spooler calls the IXPLogon::OpenStatusEntry method when a client application calls an OpenEntry method for the entry identifier in the transport provider's status table row. OpenStatusEntry opens an object with the IMAPIStatus interface associated with this particular transport provider logon. This object is then used to enable client applications to call IMAPIStatus methods, for example to reconfigure the logon session using the IMAPIStatus::SettingsDialog method, or to validate the state of the logon session using the IMAPIStatus::ValidateState method.
