(VBScript) Delete All IMAP Email

Demonstrates two ways to delete all email in a mailbox on an IMAP server.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows

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

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

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

' Turn on session logging:
imap.KeepSessionLog = 1

' 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.RubyMail")
If (success <> 1) Then
    outFile.WriteLine(imap.LastErrorText)
    WScript.Quit
End If

' Get the complete set of Uids for email in the selected mailbox.
' messageSet is a Chilkat.MessageSet
Set messageSet = imap.GetAllUids()
If (imap.LastMethodSuccess <> 1) Then
    outFile.WriteLine(imap.LastErrorText)
    WScript.Quit
End If

' Set the Deleted flag for each message.
' (ExpungeAndClose must be called to finalize the delete.)
success = imap.SetFlags(messageSet,"Deleted",1)
If (success <> 1) Then
    outFile.WriteLine(imap.LastErrorText)
    WScript.Quit
End If

' Alternatively, the Deleted flag may be set for each UID
' individiually, but this is less efficient:

n = messageSet.Count
For i = 0 To n - 1
    success = imap.SetFlag(messageSet.GetId(i),messageSet.HasUids,"Deleted",1)
    If (success <> 1) Then
        outFile.WriteLine(imap.LastErrorText)
        WScript.Quit
    End If

Next

' Expunge and close the mailbox.
success = imap.ExpungeAndClose()
If (success <> 1) Then
    outFile.WriteLine(imap.LastErrorText)
    WScript.Quit
End If

' Display the session log.
outFile.WriteLine(imap.SessionLog)

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


outFile.Close
