Convierte PST a ICS en C++

// Load the Outlook PST file
System::SharedPtr<PersonalStorage> pst = PersonalStorage::FromFile(dataDir + L"Sub.pst");
// Get the Calendar folder
System::SharedPtr<FolderInfo> folderInfo = pst->get_RootFolder()->GetSubFolder(L"Inbox");
// Loop through all the calendar items in this folder
System::SharedPtr<MessageInfoCollection> messageInfoCollection = folderInfo->GetContents();
   
{
    auto messageInfo_enumerator = (messageInfoCollection)->GetEnumerator();
    decltype(messageInfo_enumerator->get_Current()) messageInfo;
    while (messageInfo_enumerator->MoveNext() && (messageInfo = messageInfo_enumerator->get_Current(), true)){
        // Get the calendar information
        System::SharedPtr<MapiMessage> calendar = System::DynamicCast<Aspose::Email::Outlook::MapiMessage>(pst->ExtractMessage(messageInfo)->ToMapiMessageItem());
       
        // Save to disk in ICS format
        calendar->Save(L"\\Calendar\\" + calendar->get_Subject() + L"_out.ics");
    }
