Here’s the complete VBA code to auto acknowledge receipt of mail with a unique tracking number via Outlook 2016:

Sub NumberedReply(olItem As Outlook.MailItem)
Dim olOutMail As MailItem
Dim xlApp As Object
Dim xlWB As Object
Dim xlSheet As Object
Dim iLastRow As Long
Dim bXstarted As Boolean
Dim iNumber As Integer

Const strPath As String = “C:\myEmails\myLog.xlsx”
Const strMessage As String = “Your order has been received. Message reference: DKT/”

On Error Resume Next
Set xlApp = GetObject(, “Excel.Application”)
If Err <> 0 Then
Application.StatusBar = “Please wait while Excel log is opened … ”
Set xlApp = CreateObject(“Excel.Application”)
bXstarted = True
End If
On Error GoTo 0
Set xlWB = xlApp.Workbooks.Open(strPath)
Set xlSheet = xlWB.Sheets(“Sheet1”)

iLastRow = xlSheet.Range(“A” & xlSheet.Rows.Count).End(-4162).Row ‘-4162 XlDirection Enumeration

If xlSheet.Range(“A1”) = “” Then
xlSheet.Range(“A1”) = olItem.Sender
xlSheet.Range(“B1”) = 1
iNumber = 1
Else
xlSheet.Range(“A” & iLastRow + 1) = olItem.Sender
xlSheet.Range(“B” & iLastRow + 1) = xlSheet.Range(“B” & iLastRow) + 1
iNumber = Val(xlSheet.Range(“B” & iLastRow + 1))
End If

Set olOutMail = Application.CreateItem(0)
With olOutMail
.To = olItem.SenderEmailAddress
.Subject = “RE: ” & olItem.Subject
.Body = strMessage & Format(iNumber, “000000”)
‘.Display
.Send
End With
xlWB.Close SaveChanges:=True
If bXstarted Then xlApp.Quit
Set olOutMail = Nothing
Set xlSheet = Nothing
Set xlWB = Nothing
Set xlApp = Nothing
End Sub
