Outlook VBA Save email in folder name as User Defined Fields

Question

I am searching a VBA code to save outlook email as .msg file with in a specific folder which name is taken from "User Defined Filed"

In my outlook i have created a User Defined text column, each email i have write comment which is as per some relevant number.

I found a code which save the selected email and add date and time in prefix of email file name.

Public Sub SaveMessageAsMsg()
  Dim oMail As Outlook.MailItem
  Dim objItem As Object
  Dim sPath, strFolderpath As String
  Dim dtDate As Date
  Dim sName As String
  Dim enviro As String

    enviro = CStr(Environ("USERPROFILE"))
   For Each objItem In ActiveExplorer.Selection
   If objItem.MessageClass = "IPM.Note" Then
    Set oMail = objItem

  sName = oMail.Subject
  ReplaceCharsForFileName sName, "-"

  dtDate = oMail.ReceivedTime
  sName = Format(dtDate, "yyyymmdd", vbUseSystemDayOfWeek, _
    vbUseSystem) & Format(dtDate, "-hhnnss", _
    vbUseSystemDayOfWeek, vbUseSystem) & "-" & sName & ".msg"

  strFolderpath = "C:\Email Msg"
  sPath = strFolderpath & "\"
  Debug.Print sPath & sName
  oMail.SaveAs sPath & sName, olMSG

  End If
  Next

End Sub

Private Sub ReplaceCharsForFileName(sName As String, _
  sChr As String _
)
  sName = Replace(sName, "'", sChr)
  sName = Replace(sName, "*", sChr)
  sName = Replace(sName, "/", sChr)
  sName = Replace(sName, "\", sChr)
  sName = Replace(sName, ":", sChr)
  sName = Replace(sName, "?", sChr)
  sName = Replace(sName, Chr(34), sChr)
  sName = Replace(sName, "<", sChr)
  sName = Replace(sName, ">", sChr)
  sName = Replace(sName, "|", sChr)
End Sub

Please help me to use User Defined Fields as variable folder name to save emails as .msg file.
