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

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

[C# Example - Create Folder and Delete Folder]

The following example codes demonstrate how to create folder and delete folder. In order to run it correctly, please change email server, user, password, folder, file name values.


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

using System;
using System.Text;
using System.IO;
using EAGetMail; // add EAGetMail namespace

namespace receiveemail
    class Program
        static void Main(string[] args)
                // To create folder with Exchange Web Service, please change
                // ServerProtocol.Imap4 to ServerProtocol.ExchangeEWS to MailServer constructor
                // and also set oServer.SSLConnection to true

                // To create folder with Exchange WebDAV, please change
                // ServerProtocol.Imap4 to ServerProtocol.ExchangeWebDAV to MailServer constructor

                // Exchange Server supports IMAP4 protocol as well, but in Exchange 2007
                // or later version, IMAP4 service is disabled by default. If you don't want to use IMAP4
                // to manage folder from Exchange Server, you can use Exchange Web Service (Exchange 2007-2019 or
                // later version) or WebDAV (Exchange 2000/2003) protocol.

                MailServer oServer = new MailServer("",

                // Enable SSL/TLS connection, most modern email server require SSL/TLS by default
                oServer.SSLConnection = true;
                oServer.Port = 993;

                // if your server doesn't support SSL/TLS, please use the following codes
                // oServer.SSLConnection = false;
                // oServer.Port = 143;

                MailClient oClient = new MailClient("TryIt");

                // create folder
                Imap4Folder folder = oClient.CreateFolder(null, "TestFolder");

                // get existed folders.
                Imap4Folder[] folders = oClient.GetFolders();
                for (int i = 0; i < folders.Length; i++)
                    Imap4Folder fd = folders[i];
                    Console.WriteLine("folder: {0}", fd.FullPath);

                // delete folder
            catch (Exception ep)


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.


Please refer to ImapFull project for more detail.

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 2007/2010/2013/2016/2019 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 2007/2010/2013/2016/2019 or later version, please use MailClient.QueryEWSPublicFolders method.
