Command not supported by this implementation of MAPI error RRS feed

  • Question

  • Dear friends!

    We have been using Simple MAPI during many years as this:

    BEGIN_MESSAGE_MAP(CPrevPrintView, CScrollView)

    //{{AFX_MSG_MAP(CPrevPrintView)

    ...............................................

    ON_BN_CLICKED(ID_PREVIEW_MAIL, OnPreviewMail)

    ...............................................

    //}}AFX_MSG_MAP

     END_MESSAGE_MAP()

    void CPrevPrintView::OnPreviewMail() {

    TCHAR PathName[_MAX_PATH] = "MyPath", EmailAddr[_MAX_PATH] = "MyAddress", Subject[_MAX_PATH] = "MySubject";

    //Load MAPI32.DLL, get MAPISendMail addresses.

    if (!m_SimpleMAPI.InitSimpleMAPI())

    return;

    MapiMessage msgSend;

    memset(&msgSend, 0, sizeof(MapiMessage));

    MapiFileDesc fileDesc;

    memset(&fileDesc, 0, sizeof(MapiFileDesc));

    MapiRecipDesc recipDesc;

    memset(&recipDesc, 0, sizeof(MapiRecipDesc));

    msgSend.flFlags = MAPI_SENT;//The message is to be sent.

    msgSend.lpszSubject = Subject;//The message is "דוח מיכפל".

    fileDesc.lpszPathName = PathName;//Fill lpszPathName with report file name.

    fileDesc.nPosition = -1;

    // Attach report file.

    msgSend.nFileCount = 1;

    msgSend.lpFiles = &fileDesc;

    recipDesc.lpszName = EmailAddr; // Fill lpszName with E-mail address.

    recipDesc.ulRecipClass = MAPI_TO; //Indicates a primary message recipient.

    // Set mail recipient.

    msgSend.nRecipCount = 1;

    msgSend.lpRecips = &recipDesc;

    // Send mail.

    BOOL bMailerExist = TRUE;

    ULONG ulResult = m_SimpleMAPI.MAPISendMail(0, 0, &msgSend, MAPI_DIALOG | MAPI_LOGON_UI, 0L);

    m_SimpleMAPI.DeinitSimpleMAPI();

    }

    BOOL CSimpleMAPI::InitSimpleMAPI()

    {

        m_hlibMAPI = LoadLibrary(szMAPIDLL);

        if (m_hlibMAPI) {

    m_pfnMAPILogon = (LPMAPILOGON)GetProcAddress(m_hlibMAPI, "MAPILogon");

    m_pfnMAPISendMail = (LPMAPISENDMAIL)GetProcAddress(m_hlibMAPI, "MAPISendMail");

    m_pfnMAPILogoff = (LPMAPILOGOFF)GetProcAddress(m_hlibMAPI, "MAPILogoff");

    if (m_pfnMAPILogon && m_pfnMAPISendMail && m_pfnMAPILogoff)

    return TRUE;

    ........................................

    }

    else {

    ........................................

    }

    ............................................

    return FALSE;

    }

    // DeinitSimpleMAPI unloads MAPI32.DLL.

    void CSimpleMAPI::DeinitSimpleMAPI()

    {

        if (m_hlibMAPI) {

    FreeLibrary (m_hlibMAPI);

    m_hlibMAPI = NULL;

        }

    }

    It worked well but now we encountered with error 26 (command not supported). This happens

    in hebrew Windows 10 64-bit OS with Microsoft Outlook 2010 or Outlook 2016 installed after upgrade from Windows Version 1.7.0.3 to Version 1.7.0.9. We have now 8 users complained. We advised to these users return to Version 1.7.0.3 and the problem has disappeared.
