Create Folder and Manage Folder using IMAP4/Exchange Web Service (EWS)/WebDAV in Visual C++

In previous section, I introduced how to parse non-delivery report (NDR) in Visual C++. In this section, I will introduce how to create folders and manage folders with IMAP4/Exchange Web Service (EWS)/WebDAV protocol in Visual C++.

Create Folder and Delete Folder

Because IMAP4/Exchange Web Service (EWS)/WebDAV protocol supports folder access, so we can retrieve email from other mailbox rather than default “INBOX”, I have introduced it in other sections. In this section, I will introduce how to use EAGetMail to create folder and delete folder with IMAP4/Exchange Web Service/WebDAV protocol. Notice: POP3 protocol doesn’t support this feature.

[Visual C++ Example - Create Folder and Delete Folder]

The following example codes demonstrate how to create folder and delete folder.

Note

To get the full sample projects, please refer to Samples section.

#include "stdafx.h"

#include "eagetmailobj.tlh"
using namespace EAGetMailObjLib;

int _tmain(int argc, _TCHAR* argv[])
{
    const int MailServerPop3 = 0;
    const int MailServerImap4 = 1;
    const int MailServerEWS = 2;
    const int MailServerDAV = 3;

    // Initialize COM environment
    ::CoInitialize( NULL );

    try
    {
        // To create folder with Exchange Web Service, please change
        // MailServerImap4 to MailServerEWS to MailServer.Protocol

        // To create folder email with Exchange WebDAV, please change
        // MailServerImap4 to MailServerDAV to MailServer.Protocol

        // Exchange Server supports POP3/IMAP4 protocol as well, but in Exchange 2007
        // or later version, POP3/IMAP4 service is disabled by default. If you don't want to use POP3/IMAP4
        // to download email from Exchange Server, you can use Exchange Web Service(Exchange 2007/2010 or
        // later version) or WebDAV(Exchange 2000/2003) protocol.

        // For Exchange Web Service/WebDAV, please ignore
        // Port property. But for Exchange Web Service, please set SSLConnection to True

        IMailServerPtr oServer = NULL;
        oServer.CreateInstance(__uuidof(EAGetMailObjLib::MailServer));
        oServer->Server = _T("imap4.emailarchitect.net");
        oServer->User = _T("test@emailarchitect.net");
        oServer->Password = _T("testpassword");
        oServer->Protocol = MailServerImap4;

        // Set IMAP4 port
        oServer->Port = 143;

        // If your IMAP4 server requires SSL connection
        // Please add the following codes
        // oServer->SSLConnection = VARIANT_TRUE;
        // oServer->Port = 993;

        IMailClientPtr oClient = NULL;
        oClient.CreateInstance(__uuidof(EAGetMailObjLib::MailClient))
        oClient->LicenseCode = _T("TryIt");

        oClient->Connect( oServer );
        _tprintf(_T("Connected\r\n"));
        IImap4FolderPtr oFolder = oClient->CreateFolder( NULL, _T("Test Folder"));

        _variant_t vtFolder = oClient->Imap4Folders ;
        SAFEARRAY *psa = vtFolder.parray;
        LONG UBound = 0, LBound = 0;
        SafeArrayGetLBound( psa, 1, &LBound );
        SafeArrayGetUBound( psa, 1, &UBound );
        for( long i = LBound; i <= UBound; i++ )
        {
            _variant_t vt;
            SafeArrayGetElement( psa, &i, &vt );
            IImap4FolderPtr fd;
            vt.pdispVal->QueryInterface( __uuidof(IImap4Folder), (void**)&fd);

            _tprintf( _T("folder: %s\r\n"), (TCHAR*)fd->FullPath );
        }

        oClient->DeleteFolder( oFolder );
        oClient->Logout();

    }
    catch( _com_error &ep )
    {
        _tprintf( _T("Error: %s"), (const TCHAR*)ep.Description());
    }

    return 0;
}

Retrieve/Copy/Move/Upload Email to Folder

To retrieve emails from a specified folder, please use SelectFolder method; To move email from a folder to another folder, please use Move method; To copy email from a folder to another folder, please use Copy method; To upload an email file from local disk to server folder, please use Append method.

Access Exchange Shared Mailbox

A MS Exchange shared mailbox is a mailbox that multiple users can use to read and send email messages. To access shared mailbox, please use MailServer.Alias property.

Access Exchange 2007/2010/2013/2016 Public Mailbox

Since Exchange 2007 or later version (2010/203), IMAP4 protocol does not expose public folders to mail client. If you want to access public folders on MS Exchange 2007/2010/2013/2016 or later version, please use MailClient.QueryEWSPublicFolders method.
