Get mail folder changes

The following example shows you how to use delta query to track changes to mail folders.

C++ example

#include <iostream>

#include "independentsoft/graph/graph_client.hpp"
#include "independentsoft/graph/graph_exception.hpp"
#include "independentsoft/graph/mails/mail_folder.hpp"
#include "independentsoft/graph/mails/mail_folder_changes.hpp"
#include "independentsoft/graph/users/user_id.hpp"

using namespace independentsoft::graph;
using namespace independentsoft::graph::mails;
using namespace independentsoft::graph::users;

int main()
{
    try
    {
        GraphClient client;

        client.client_id = "63333333-209e-454e-b7bd-55a4d201270f";
        client.tenant = "independentsoft.onmicrosoft.com";
        client.client_secret = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";

        MailFolderChanges changes = sync_wait(client.get_mail_folder_changes(UserId("info@independentsoft.onmicrosoft.com")));

        for (std::size_t i = 0; i < changes.mail_folders.size(); i++)
        {
            std::cout << "DisplayName = " << changes.mail_folders[i].display_name << std::endl;
            std::cout << "Id = " << changes.mail_folders[i].id << std::endl;
            std::cout << "" << std::endl;
        }

        std::cout << "DeltaLink = " << changes.delta_link << std::endl;
    }
    catch (const GraphException& ex)
    {
        std::cout << "Error: " << ex.code << std::endl;
        std::cout << "Message: " << ex.message << std::endl;
    }

    return 0;
}
