$oImap = ObjCreate("Chilkat.Imap")

; Connect to an IMAP server.
; Use TLS
$oImap.Ssl = True

; Select an IMAP mailbox
$bSuccess = $oImap.SelectMailbox("Inbox")
If ($bSuccess <> True) Then

; After selecting the mailbox. the total number of emails
; is immediately available:

; To determine the number of unseen messages, a call
; to Search is required, which returns the set of UIDs
; of all unseen messages.

; We can choose to fetch UIDs or sequence numbers.
