Code below. Everything in DllMain succeeds. But my hookproc is never called.
Any ideas?

LRESULT CALLBACK CallWndProc(INT nCode, WPARAM wParam, LPARAM lParam )
{
    Beep(880,100);
    return CallNextHookEx(hHook, nCode, wParam, lParam);
}

BOOL WINAPI DllMain( HINSTANCE hinstDLL, DWORD fdwReason, LPVOID lpvReserved )
{
    static BOOL bInit = FALSE;
    if ( !bInit )
    {
        Beep(440,300); // I hear this one!

        HMODULE hUser32 = GetModuleHandle(L"user32.dll");
        if ( hUser32 == NULL ) Beep(880,200);

        pFindWindowW = ( FWW_TYPE ) GetProcAddress(hUser32, "FindWindowW");
        if ( pFindWindowW == NULL ) Beep(880,200);

        hWndOL = pFindWindowW(L"rctrl_renwnd32", L"Inbox - Microsoft Outlook");
        if ( hWndOL == NULL ) Beep(880,200);

        pSetWindowsHookEx = (SWHEx_TYPE) GetProcAddress(hUser32,
            "SetWindowsHookExW");
        if ( pSetWindowsHookEx == NULL ) Beep(880,200);

        pGetWindowThreadProcessId = (GWTPI_TYPE) GetProcAddress(hUser32,
            "GetWindowThreadProcessId");
        if ( pGetWindowThreadProcessId == NULL ) Beep(880,200);

        hHook = pSetWindowsHookEx(WH_CALLWNDPROC, (HOOKPROC) CallWndProc,
            NULL, pGetWindowThreadProcessId(hWndOL, NULL));
        if ( hHook == NULL ) Beep(880,200);

        bInit = TRUE;
    }
    return TRUE;
}
