AutoIt Requires Chilkat v11.0.0+

Mark IMAP Email as Read/Unread (Seen/Unseen)

Demonstrates how to mark emails as read or unread. AutoIt

Local $bSuccess = False

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

$oImap = ObjCreate("Chilkat.Imap")

;  Connect to an IMAP server.
;  Use TLS
$oImap.Ssl = True
$oImap.Port = 993
$bSuccess = $oImap.Connect("imap.example.com")
If ($bSuccess = False) Then
    ConsoleWrite($oImap.LastErrorText & @CRLF)
    Exit
EndIf

;  Login
$bSuccess = $oImap.Login("myLogin","myPassword")
If ($bSuccess = False) Then
    ConsoleWrite($oImap.LastErrorText & @CRLF)
    Exit
EndIf

;  Select an IMAP mailbox
$bSuccess = $oImap.SelectMailbox("Inbox")
If ($bSuccess = False) Then
    ConsoleWrite($oImap.LastErrorText & @CRLF)
    Exit
EndIf

;  Set PeekMode so that downloaded messages are not
;  automatically marked as seen.
$oImap.PeekMode = True

;  The NumMessages property contains the number of messages 
;  in the currently selected mailbox.
Local $iNumMsgs = $oImap.NumMessages
If ($iNumMsgs = 0) Then
    Exit
EndIf

$oEmail = ObjCreate("Chilkat.Email")
Local $i
For $i = 1 To $iNumMsgs
    ;  Download each email by sequence number (not UID)
    $bSuccess = $oImap.FetchEmail(False,$i,False,$oEmail)
    If ($bSuccess = False) Then
        ConsoleWrite($oImap.LastErrorText & @CRLF)
        Exit
    EndIf

    ;  If desired, mark the email as SEEN.  There are two
    ;  ways to do it:

    ;  1) Set the flag directly by using the sequence number
    ;  Indicate that we are passing a sequence number and
    ;  not a UID:
Local $bIsUid = False
    ;  Set the SEEN flag = 1 to mark the email as SEEN,
    ;  or set it to 0 to mark it as not-seen.
    $bSuccess = $oImap.SetFlag($i,$bIsUid,"SEEN",1)
    If ($bSuccess = False) Then
        ConsoleWrite($oImap.LastErrorText & @CRLF)
        Exit
    EndIf

    ;  2) Alternatively, we can use the email object.
    ;  When an email is downloaded from the IMAP server
    ;  Chilkat will add a "ckx-imap-uid" header to the email.
    ;  This makes it possible to know the UID associated with
    ;  the email.  (This is not the sequence number, which may change
    ;  from session to session, but the UID which does not change.
    ;  The SetMailFlag method is identical to SetFlag, except
    ;  it gets the UID from the ckx-imap-uid header.
    ;  For example:
    $bSuccess = $oImap.SetMailFlag($oEmail,"SEEN",1)
    If ($bSuccess = False) Then
        ConsoleWrite($oImap.LastErrorText & @CRLF)
        Exit
    EndIf

Next

;  Disconnect from the IMAP server.
$bSuccess = $oImap.Disconnect()
