Sub apscan()

    Dim olApp As Object
    Dim ns As Object
    Dim folder As Object
    Dim objItems As Object
    Dim objItem As Object
    Dim atmt As Object
    Dim i As Long

    Set olApp = CreateObject("Outlook.Application")
    Set ns = olApp.GetNamespace("MAPI")
    Set folder = ns.GetDefaultFolder(6) ' 6 = olFolderInbox
    Set objItems = folder.Items

    objItems.Sort "[ReceivedTime]", True

    For Each objItem In objItems
        If TypeName(objItem) = "MailItem" Then
            For Each atmt In objItem.Attachments
                Debug.Print atmt.Filename
            Next atmt
        End If
    Next objItem

    Set atmt = Nothing
    Set objItem = Nothing
    Set objItems = Nothing
    Set folder = Nothing
    Set ns = Nothing
    Set olApp = Nothing

End Sub
