Create Folder and Manage Folder using IMAP4/Exchange Web Service (EWS)/WebDAV in VB.NET

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

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.

[VB.NET Example - Create Folder and Delete Folder]

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


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

Imports System.IO
Imports EAGetMail 'imports EAGetMail namespace

Module Module1
    Sub Main()

        ' 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 2007/2010 or
        ' later version) or WebDAV (Exchange 2000/2003) protocol.

        ' For Exchange Web Service/WebDAV protocol, please ignore port property
        ' and use domain\user as the user name.
        Dim oServer As New MailServer("", _
            "", "testpassword", ServerProtocol.Imap4)
        Dim oClient As New MailClient("TryIt")

        ' Set IMAP4 server port
        oServer.Port = 143

        ' If your IMAP4 server requires SSL connection,
        ' Please add the following codes:
        ' oServer.SSLConnection = True
        ' oServer.Port = 993


            Dim folder As Imap4Folder = oClient.CreateFolder(Nothing, "TestFolder")

            Dim folders() As Imap4Folder = oClient.Imap4Folders
            Dim count As Integer = folders.Length
            For i As Integer = 0 To count - 1
                Dim fd As Imap4Folder = folders(i)
                Console.WriteLine("folder: {0}", fd.FullPath)


        Catch ep As Exception
        End Try

    End Sub
End Module

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.
