Interact with Webpage from Outlook

I have the following code which successfully opens a hyperlink in internet explorer from an email in Outlook.

My next question is how do I interact with the webpage?

For example I would like to select option 83 from ID "ctl00_cph_MAIN_ddlHCLaction" which is a dropdown.

I have tried

oIE.document.GetElementbyID("ctl00_cph_MAIN_ddlHCLaction").value = 83

Select allOpen in new window

but I get the error

'Run-time error '-2147467259 (80004005)': method 'document' of object 'IWebBrowser2' failed.'

Sub macro()

Dim regex
    Set objOL = CreateObject("Outlook.Application")
    Set NewMail = objOL.ActiveExplorer.Selection.Item(1)
    NewMail.Display
    res = NewMail.Body
    
    Set regex = CreateObject("VBScript.RegExp")

    With regex
        .Global = False
        .MultiLine = False
        .IgnoreCase = True
        .Pattern = "HYPERLINK ""([^""]+?)""Click here to access enquiry"
    End With
    Set mtches = regex.Execute(res)
        If mtches.Count > 0 Then
            strHL = mtches(0).submatches(0)
            Set oIE = New InternetExplorerMedium
            oIE.navigate strHL, CLng(2048)
            oIE.Visible = True
        End If
End Sub
