Open existing PST in write mode

The following example shows you how to open an existing PST file in read/write mode, add folders and items, and save the changes back to the same file. New items are built from a independentsoft::msg::Message and wrapped in an independentsoft::pst::Item.

C++ example

#include <iostream>
#include <optional>
#include <vector>

#include "independentsoft/msg/message.hpp"
#include "independentsoft/pst/pst_file.hpp"
#include "independentsoft/pst/folder.hpp"
#include "independentsoft/pst/item.hpp"
#include "independentsoft/pst/enums.hpp"

using namespace independentsoft::pst;

int main()
{
    PstFile file("c:\\testfolder\\Outlook.pst", PstAccess::ReadWrite);

    Folder* startFolder = file.mailbox_root();

    Folder projects(text(u"Projects"));
    startFolder->add_folder(projects);

    std::optional<Folder> projectsFolder = startFolder->get_folder(text(u"Projects"));

    msg::Message message1;
    message1.set_message_class(text(u"IPM.Note"));
    message1.set_subject(text(u"Project kickoff"));
    message1.set_body(text(u"First meeting notes."));

    msg::Recipient recipient1;
    recipient1.displayName = text(u"Jane Doe");
    recipient1.emailAddress = text(u"jane.doe@example.com");
    recipient1.recipientType = msg::RecipientType::To;
    message1.recipients().push_back(recipient1);

    msg::Message message2;
    message2.set_message_class(text(u"IPM.Note"));
    message2.set_subject(text(u"Project update"));
    message2.set_body(text(u"Status update for the project."));

    msg::Recipient recipient2;
    recipient2.displayName = text(u"John Smith");
    recipient2.emailAddress = text(u"john.smith@example.com");
    recipient2.recipientType = msg::RecipientType::To;
    message2.recipients().push_back(recipient2);

    std::vector<Item> items;

    Item item1(message1);
    items.push_back(item1);

    Item item2(message2);
    items.push_back(item2);

    if (projectsFolder)
    {
        projectsFolder->add_items(items);

        Folder archive(text(u"Archive"));
        projectsFolder->add_folder(archive);
    }

    file.save();

    std::cout << "Done." << std::endl;
    return 0;
}
