While I agree with what's mentioned in the answers below, suggesting that this is a very bad design for a Userform unless copious amounts of error checks are included...

to accomplish what you need to do, with minimal changes to your code, there are two approaches.

1. Use KeyUp() event instead of Change event for the textbox. Here is an example:

   Private Sub TextBox2_KeyUp(ByVal KeyCode As MSForms.ReturnInteger, ByVal Shift As Integer)
   
       Dim TextStr As String
       TextStr = TextBox2.Text
   
       If KeyCode <> 8 Then ' i.e. not a backspace
   
           If (Len(TextStr) = 2 Or Len(TextStr) = 5) Then
               TextStr = TextStr & "/"
           End If
   
       End If
       TextBox2.Text = TextStr
   End Sub
   

2. Alternately, if you need to use the Change() event, use the following code. This alters the behavior so the user keeps entering the numbers, as

   12072003
   

while the result as he's typing appears as

    12/07/2003

But the '/' character appears only once the first character of the DD i.e. 0 of 07 is entered. Not ideal, but will still handle backspaces.

    Private Sub TextBox1_Change()
        Dim TextStr As String

        TextStr = TextBox1.Text

        If (Len(TextStr) = 3 And Mid(TextStr, 3, 1) <> "/") Then
            TextStr = Left(TextStr, 2) & "/" & Right(TextStr, 1)
        ElseIf (Len(TextStr) = 6 And Mid(TextStr, 6, 1) <> "/") Then
            TextStr = Left(TextStr, 5) & "/" & Right(TextStr, 1)
        End If

        TextBox1.Text = TextStr
    End Sub
