#  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.

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

    #  ... your application may process each MIME string...
}

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

for ($i = 1; $i -le $n; $i++) {

    #  Download the email by sequence number.
    $email = $imap.FetchSingle($i,$bUid)

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

}

#  Disconnect from the IMAP server.
