Automatically export specific emails to text file from Outlook

I am trying to use a VBA script to automatically export all incoming emails with a specific subject to text files that I will then parse with a Python script. The code below works for the most part, but it will randomly skip some of the emails come in.

I haven't found any reason as to why this is, and it doesn't skip emails from the same sender each day, it varies.

We have about 20-30 emails coming in during a 30 minute period or so if that matters. I'd love some help with this.

Private Sub Items_ItemAdd(ByVal Item As Object)
Dim strSubject As String
strSubject = Item.Subject
  If TypeOf Item Is Outlook.MailItem And strSubject Like "VVAnalyze Results" Then
    SaveMailAsFile Item
  End If
End Sub

Private Sub SaveMailAsFile(oMail As Outlook.MailItem)
  Dim dtDate As Date
  Dim sName As String
  Dim sFile As String
  Dim sExt As String

  sPath = "C:\Users\ltvstatus\Desktop\Backup Reports\"
  sExt = ".txt"
  sName = oMail.Subject
  ReplaceCharsForFileName sName, "_"
  dtDate = oMail.ReceivedTime
  sName = Format(dtDate, "yyyymmdd", vbUseSystemDayOfWeek, _
    vbUseSystem) & Format(dtDate, "-hhnnss", _
    vbUseSystemDayOfWeek, vbUseSystem) & "-" & sName & sExt

  oMail.SaveAs sPath & sName, olSaveAsTxt
End Sub

Your code looks okay to me so I am not sure if your overwriting your saved emails with new one or your getting to many emails at once while the code is processing one and skipping the other...

I have modified your code to loop in your Inbox and added Function to create new file name if the file already exist...

if you receive 10 email in 1 second, the function will create FileName(1).txt, FileName(2).txt and so on...

I will also advise you to move the emails to subfolder as you SaveAs txt...

Item.Move Subfolder

CODE UPDATED

Option Explicit
Private WithEvents Items As Outlook.Items
Private Sub Application_Startup()
    Dim olNs As Outlook.NameSpace
    Dim Inbox  As Outlook.MAPIFolder

    Set olNs = Application.GetNamespace("MAPI")
    Set Inbox = olNs.GetDefaultFolder(olFolderInbox)
    Set Items = Inbox.Items
End Sub

Private Sub Items_ItemAdd(ByVal Item As Object)
    If TypeOf Item Is Outlook.MailItem Then
        SaveMailAsFile Item ' call sub
    End If
End Sub

    Path = Environ("USERPROFILE") & "\Desktop\Backup Reports\"
    ItemSubject = Item.Subject
    RevdDate = Item.ReceivedTime
    Ext = "txt"

    For i = Items.Count To 1 Step -1
        Set Item = Items.Item(i)

        DoEvents

        If Item.Class = olMail Then

                                            Item.Subject & Ext

            Item.SaveAs Path & ItemSubject, olTXT
            Item.Move SubFolder

    End If

    Exit Function
End Function
