Using Imap4 to access Office365 Email

Using Imap4 to access Office365 Email

Before the company moved to Office365, we used to be able to connect to the Exchange Server using Imap4 as follows:


Private Sub ReadOutlookEMail()
        Dim imap4 As MailServer = New MailServer(ExchangeServerName, UserName, Password, True, ServerAuthType.AuthLogin, ServerProtocol.Imap4)
        Dim oClient As MailClient = New MailClient("EG-AA1150422356-00388-F5A76D10CFC47CDB1B19F84C66DF4C8E")
        Dim messageSubject As String = String.Empty
        Dim messageBody As String = String.Empty

            Dim infos() As MailInfo = oClient.GetMailInfos()

            For iIndex As Integer = infos.Length - 50 To infos.Length - 1
                Dim info As MailInfo = infos(iIndex)
                Dim oMail As Mail = oClient.GetMail(info)

                messageSubject = oMail.Subject
                messageBody = oMail.TextBody

                    If (oMail.Attachments.Length > 0) Then
                        For Each att As EAGetMail.Attachment In oMail.Attachments
                            Dim sFileName As String
                            sFileName = messageBody.Substring(messageBody.IndexOf("From Date") + 10, 8)
                            sFileName = "C:\" & sFileName.Replace("/", "-") & ".CSV"
                            If Not File.Exists(sFileName) Then
                                att.SaveAs(sFileName, False)
                            End If
                    'End If
            Next iIndex

        Catch ex As Exception
            SendMail("An error ocurred while reading E-Mail" & ex.Message)

        End Try
    End Sub 

I tried connecting to Iffice365 as follows, but it just hangs:


Dim imap4 As MailServer = New MailServer("outlook.office365.com", UserName, Password, True, ServerAuthType.AuthLogin, ServerProtocol.Imap4) 

Any ideas?
