Create email in Outlook Express 429 error

[RV]

I'm trying to generate an email in Outlook Express version 6.00.2800.1123
Acces version is Access97 SR2.

I want to use the CreateObject method ,not the SendObject method.
I've created a form with a button.
This is the VBA code attached to the On Click event of the button:

Private Sub Knop0_Click()

Dim OutApp As Outlook.Application
Dim OutMail As Outlook.MailItem
Dim strBODY As String

Set OutApp = CreateObject("Outlook.Application")
Set OutMail = OutApp.CreateItem(olMailItem)
OutApp.Visible = True

    With OutMail
    
        .To = "nep@adres.nl"
        .CC = ""
        .BCC = ""
        .Subject = "TEST TEST TEST"
        .Body = strBODY
        .Send
    End With

End Sub

When the code is run, this error pops up:

Error 429, ActiveX can't create object.
This line is marked:

Set OutApp = CreateObject("Outlook.Application")

I understand this most probably is caused by a Reference which should by added through Options -> References.
The problem is, WHICH Reference would be needed?
I tried these References, no success:

• Microsoft Outlook 8.0 Object Library
• Microsoft Outlook 9.0 Object Library

Any help would be appreciated.

Greetings,

RV
