=====================================================

Sub GetFromInbox()

    Dim olApp As Outlook.Application
    Dim olNs As Namespace
    Dim Fldr As MAPIFolder
    Dim olMail As Variant
    Dim i, ij As Integer
    Dim tt As Date

    Set olApp = New Outlook.Application
    Set olNs = olApp.GetNamespace("MAPI")
    Set Fldr = olNs.GetDefaultFolder(olFolderInbox)
    i = 1
    ij = 0
    x = Date

    ' Now. the following "For each next " code starts to look in the oldest email!
   


    For Each olMail In Fldr.Items
        ij = ij + 1
        'If IsNumeric((Format(olMail.ReceivedTime, "dd/mm/yy"))) Then
            Sheets("test").Range("a1").Select
            Sheets("test").Range("I1").Clear
            Sheets("test").Range("I2") = ij
            Sheets("test").Range("I1").Value = (Format(olMail.ReceivedTime, "dd/mm/yy"))
            Sheets("test").Range("I1").NumberFormat = "dd/mm/yy"
            tt = Sheets("test").Range("I1")
            ' MsgBox ("Y-tt=" & tt & " receivedtime=" & olMail.ReceivedTime)
        'Else
            'tt = 0
            'MsgBox ("N-tt=" & tt & " receivedtime=" & olMail.ReceivedTime)
        'End If
        ' tt = CDate(Format(olMail.ReceivedTime, "dd/mm/yy"))
        If tt >= Range("H1") Then
            'If InStr(olMail.Subject, "others") > 0 And tt >= Range("h1") Then
            If InStr(olMail.Subject, "others") > 0 Then
                ActiveSheet.Range("h2") = "y"
                ActiveSheet.Cells(i, 1).Value = olMail.Subject
                ActiveSheet.Cells(i, 2).Value = olMail.ReceivedTime
                ActiveSheet.Cells(i, 3).Value = olMail.SenderName
                tt = CDate(Format(olMail.ReceivedTime, "dd/mm/yy"))
                ActiveSheet.Cells(i, 4).Value = CDate(Format(olMail.ReceivedTime, "dd/mm/yy"))
                ' tt = ActiveSheet.Cells(i, 4).Value
                ActiveSheet.Cells(i, 5).Value = (Format(olMail.ReceivedTime, "hh:mm"))
                MsgBox ("tt=" & tt)
                i = i + 1
            End If
        Else
            Sheets("test").Range("h2") = "N"
        End If
    Next olMail

    Set Fldr = Nothing
    Set olNs = Nothing
    Set olApp = Nothing
    'tt = ""
