Dim fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
'Create a Unicode (utf-16) output text file.
Set outFile = fso.CreateTextFile("output.txt", True, True)

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Imap")
set imap = CreateObject("Chilkat.Imap")

' This example requires the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

' Connect to an IMAP server.
' Use TLS
imap.Ssl = 1
imap.Port = 993
success = imap.Connect("imap.someMailServer.com")
If (success <> 1) Then
    outFile.WriteLine(imap.LastErrorText)
    WScript.Quit
End If

' Login
success = imap.Login("myLogin","myPassword")
If (success <> 1) Then
    outFile.WriteLine(imap.LastErrorText)
    WScript.Quit
End If

' Select an IMAP mailbox
success = imap.SelectMailbox("Inbox")
If (success <> 1) Then
    outFile.WriteLine(imap.LastErrorText)
    WScript.Quit
End If

' Once the mailbox is selected, the NumMessages property
' will contain the number of messages in the mailbox.
' You may loop from 1 to NumMessages to
' fetch each message by sequence number.

bUid = 0

n = imap.NumMessages
For i = 1 To n

    ' Download the email by sequence number.
    mimeStr = imap.FetchSingleAsMime(i,bUid)

    ' ... your application may process each MIME string...
Next

' An alternative is to download each email in the form of an
' email object, like this:

For i = 1 To n

    ' Download the email by sequence number.
    ' email is a Chilkat.Email
    Set email = imap.FetchSingle(i,bUid)

    ' ... your application may process the email object...

Next

' Disconnect from the IMAP server.
success = imap.Disconnect()
