I have posted this on Mr Excel too Code to read Outlook mail with specific subject | MrExcel Message Board
So, apologies for cross posting!
Admins, Please delete it, if this should not be done.

I have this working code which reads the mail and its attachment into a local folder. It is working well.
But a new requirement is to read the mails with subject containing the words, Customer ID 1000 - Smith, JOHN P, where the word Customer ID is always static but the number and name is dynamic.
I am not sure how to resolve this as my modified code does not read the mail which contains the word, Customer ID.

Private Sub cmdOutlook_Click()
Dim olApp As Object
Dim MYFOLDER As Object
Dim OlItems As Object
Dim olMail As Object
Dim x As Integer
Dim subject As String
Dim strFile As String
Dim strFolderpath As String
Dim objDestfolder As Object
Dim filterKeywords As String
Dim filter As String

Set olApp = GetObject(, "Outlook.Application")
If Err.Number = 429 Then
    Set olApp = CreateObject("Outlook.Application")
End If

strFolderpath = "C:\Users\Testing"
'On Error Resume Next

' Set the Attachment folder.
strFolderpath = strFolderpath & "\Attachments\"

Set MYFOLDER = olApp.GetNamespace("MAPI").Folders("Customer Mailbox").Folders("Inbox")

 Set OlItems = MYFOLDER.Items

  'Working code
  'For Each OlMail In OlItems
        'strFile = OlMail & ".XML"
        'strFile = strFolderpath & strFile
        'If OlMail.Attachments.Count > 0 Then
            'For x = 1 To OlMail.Attachments.Count
                'OlMail.Attachments.item(x).SaveAsFile strFile
            'Next x
        'End If

'Modified code
 For i = OlItems.Items.Count To 1 Step -1
        If TypeOf OlItems.Items(i) Is MailItem Then
            Set olMail = OlItems.Items(i)
            If InStr(olMail.subject, "Customer ID") > 0 Then ' how to use the Like condition here?
                strFile = strFolderpath & strFile
                If olMail.Attachments.Count > 0 Then
                    For x = 1 To olMail.Attachments.Count
                            olMail.Attachments.Item(x).SaveAsFile strFile
                    Next x
                End If
        End if
    End if

Set MYFOLDER = Nothing
Set olMail = Nothing
Set OlItems = Nothing
Set olApp = Nothing
