VBA code update from Outlook 2016 to 2013 - vba

Question

I wrote this code on an other PC which had Win10 and Office 2016. It is used in an outlook rule. It saves the xml files from the e-mail to a folder and change it to xlsx file in an other folder. In Outlook 2016 it runs properly. I copied it to an other notebook.
This notebook has Win10 and Office 2013 and this code run in Outlook 2013 without any error message but the xml files neither were saved into the given folder and nor were converted to xlsx.
What could be wrong in this code?
Option Explicit
Public Sub saveconvAttachtoDisk(itm As Outlook.MailItem)
Dim objAtt As Outlook.Attachment
Dim saveFolder As String
Dim dateFormat As String
Dim convFormat As String
Dim objFSO As Object
Dim objFolder As Object
Dim objFile As Object
saveFolder = "C:\Users\tulaj\Documents\xml\"
convFolder = "C:\Users\tulaj\Documents\xls\"
dateFormat = Format(itm.ReceivedTime, "yyyy-mm-dd HH-mm-ss")
For Each objAtt In itm.Attachments
objAtt.SaveAsFile saveFolder & dateFormat & objAtt.FileName
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFolder = objFSO.GetFolder(saveFolder)
If UCase(Right(objAtt.FileName, Len(XML))) = UCase(XML) Then
NewFileName = convFolder & dateFormat & objAtt.FileName & "_conv.xlsx"
Set ConvertThis = Workbooks.Open(saveFolder & dateFormat & objAtt.FileName)
ConvertThis.SaveAs FileName:=NewFileName, FileFormat:= _
xlOpenXMLWorkbook
ConvertThis.Close
End If
Next
Set objAtt = Nothing
End Sub

This should work for you...
Option Explicit
Public Sub saveconvAttachtoDisk(itm As Outlook.MailItem)
Dim objAtt As Outlook.Attachment
Dim SaveFolder As String
Dim convFolder As String
Dim DateFormat As String
Dim ConvFormat As String
Dim NewFileName As String
Dim ConvertThis As Object
Dim objFSO As Object
Dim objFolder As Object
Dim objFile As Object
SaveFolder = "C:\Temp\xml\"
convFolder = "C:\Temp\xls\"
DateFormat = Format(itm.ReceivedTime, "yyyy-mm-dd HH-mm-ss ")
For Each objAtt In itm.Attachments
Debug.Print objAtt.FileName
objAtt.SaveAsFile SaveFolder & DateFormat & objAtt.FileName
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFolder = objFSO.GetFolder(SaveFolder)
If UCase(Right$(objAtt.FileName, Len("XML"))) = UCase("XML") Then
NewFileName = convFolder & DateFormat & objAtt.FileName & "_conv.xlsx"
Set ConvertThis = Workbooks.Open(SaveFolder & DateFormat & objAtt.FileName)
ConvertThis.SaveAs FileName:=NewFileName, FileFormat:= _
xlOpenXMLWorkbook
ConvertThis.Close
End If
Next
Set objAtt = Nothing
End Sub
To Test it, select the Email and run the following code
Public Sub Test_Rule()
Dim Item As MailItem
Set Item = ActiveExplorer.Selection.Item(1)
saveconvAttachtoDisk Item
Set Item = Nothing
End Sub
