EntryID property of Outlook Emails

[jrpfinch]

When I run this code in Access:

Public Sub OpenOutlookEmail(ByVal strEntryID As String)
    
    Dim objOutlook As Outlook.Application
    Dim objNameSpace As Outlook.NameSpace
    Dim objCSIFolder As Outlook.MAPIFolder
    Dim objDisplayEmail As Outlook.MailItem
    Dim objFolders As Outlook.Folders
    
    Set objOutlook = New Outlook.Application
    Set objNameSpace = objOutlook.GetNamespace("MAPI")
    Set objFolders = objNameSpace.Folders
    Set objCSIFolder = OpenOutlookFolder("Public Folders\All Public Folders\A\B\C\D", objFolders)
    Set objDisplayEmail = objCSIFolder.Items.Find("[EntryID] = '" & strEntryID & "'")
    
    If TypeName(objDisplayEmail) <> "Nothing" Then
        objDisplayEmail.Display 'THE USE CAN MAKE CHANGES AND SAVE THEM TO OUTLOOK
    Else
        MsgBox "Email not found in Outlook!", vbOKOnly + vbExclamation
    End If

End Sub

I get the message:

Run-time error '-1214119927 (b7a20009)'
The property "EntryID" in the condition is not valid

I would be very grateful if someone could tell me where I have gone wrong. I have tried several permutations of filter
