How to fix "Cannot save free/busy information"

Hi Experts,

I need Experts help. The attached script shows "Cannot save free/busy information" when I run the script. I'm using this script for sending email with Calendar.

Experts has advised me to use cleanfreebusy switch, but the problem is I have no idea how to do this. Hope Experts can help me. Attached the script together with my workbook.

Sub SendEmail2()
Dim olkApp As Object
Dim MItem As Object
Dim olkAppointment As Object
  
Dim cell As Range
Dim Subj As String
Dim EmailAddr As String
Dim Adate As Date
Dim Atime As String
Dim Msg As String
Dim Msg2 As String
Dim SendStatus As String
Dim FileLocation As String
Dim strApptBody As String

Const olAppointmentItem As Integer = 1
Const olBusy As Integer = 2
Const olICal As Integer = 8
Const olMailItem As Integer = 0
      
  'Loop through the rows
  For Each cell In Columns("H").Cells.SpecialCells(xlCellTypeConstants)
    If cell.Value Like "*@*" Then
    
      'Get the data
      SendStatus = cell.Offset(0, 1)
      If SendStatus <> "To be sent" Then GoTo NotThisOne
      Subj = cell.Offset(0, -1).Value
      EmailAddr = cell.Value
      Adate = cell.Offset(0, -6).Value
      Atime = cell.Offset(0, -5).Value
      FileLocation = "C:\ApptFiles\OutlookAppointment.ics"
'FileLocation = Environ("temp") & "\" & "OutlookAppointment.ics"
    cell.Offset(0, 1).Value = "Sent"
   
    Set olkApp = CreateObject("outlook.application")
    Set olkAppointment = olkApp.CreateItem(olAppointmentItem)

        'Both options keep the just-created .ics file
