And I'm apparently suffering from a common problem - how to get Outlook to
shutdown after my add-in is installed. I've flailed for a couple of days,
now it's time to ask for help. I've gleaned that I need to somehow close or
release or free something in the OnClose event for the Explorer, but what and
how is that done? I've tried doing
appPtr-GetApplication()-Release()...which doesn't seem to have any effect.
Here's the OnConnection() code where some of the initialization code lives,
if it helps to point out my failures...

STDMETHODIMP CConnect::OnConnection(IDispatch *pApplication,
AddInDesignerObjects::ext_ConnectMode ConnectMode, IDispatch *pAddInInst,
SAFEARRAY ** /*custom*/ )
{
pApplication-QueryInterface(__uuidof(IDispatch), (LPVOID*)&m_pApplication);

CComQIPtr Outlook::_Application spApp(pApplication);
ATLASSERT(spApp);
m_spApp = spApp;

CComPtrOutlook::_Explorer spExplorer;

spExplorer = spApp-ActiveExplorer();
m_spExplorer = spExplorer;

ExpEvents:ispEventAdvise((IDispatch*)m_spExplore r,&__uuidof(Outlook::ExplorerEvents));

AppEvents:ispEventAdvise((IDispatch*)m_spApp,&__ uuidof(Outlook::ApplicationEvents));

return S_OK;
}
