The following example codes demonstrate how to download emails from Hotmail/Outlook/Office365 account using IMAP4 protocol. In order to run it correctly, please change email server, user, password, folder, file name value to yours.


To get full sample projects, please download and install EAGetMail on your machine.

#include "stdafx.h"

using namespace System;
using namespace System::IO;
using namespace EAGetMail; //add EAGetMail namespace

int main(array<System::String ^> ^args)
    // Create a folder named "inbox" under current directory
    // to save the email retrieved.
    String ^curpath = Directory::GetCurrentDirectory();
    String ^mailbox = String::Format("{0}\\inbox", curpath);

    // If the folder is not existed, create it.
    if (!Directory::Exists(mailbox))

    // Hotmail/Outlook IMAP4 server is ""
    MailServer ^oServer = gcnew MailServer("",
        "", "yourpassword", ServerProtocol::Imap4);

    // For office 365 user, please change server to:
    // MailServer ^oServer = gcnew MailServer("",
    //     "user@domain", "yourpassword", ServerProtocol::Imap4);

    MailClient ^oClient = gcnew MailClient("TryIt");

    // Enable SSL connection
    oServer->SSLConnection = true;

    // Set 993 IMAP4 SSL port
    oServer->Port = 993;

        array<MailInfo^> ^infos = oClient->GetMailInfos();
        for (int i = 0; i < infos->Length; i++)
            MailInfo ^info = infos[i];
            Console::WriteLine("Index: {0}; Size: {1}; UIDL: {2}",
                info->Index, info->Size, info->UIDL);

            // Receive email from Hotmail POP3 server
            Mail ^oMail = oClient->GetMail(info);

            Console::WriteLine("From: {0}", oMail->From->ToString());
            Console::WriteLine("Subject: {0}\r\n", oMail->Subject);

            // Generate an email file name based on date time.
            System::DateTime d = System::DateTime::Now;
            System::Globalization::CultureInfo ^cur = gcnew
            String ^sdate = d.ToString("yyyyMMddHHmmss", cur);
            String ^fileName = String::Format("{0}\\{1}{2}{3}.eml",
                mailbox, sdate, d.Millisecond.ToString("d3"), i);

            // Save email to local disk
            oMail->SaveAs(fileName, true);
