VBA Outlook to get the user name of who modified an entry in a shared public folder for contacts last

Can someone help advise how I can locate using VBA for Outlook the user name of who modified an entry in a shared public folder for contacts?

I can easily get the contact details for everything else from the ContactItem including date modified (LastModificationTime Property), but the name of the user at the bottom of the screen is not in the ContactItem and must be elsewhere?

I have looked at the examples for SharePoint in other forums but cannot work out how to apply it in Outlook VBA.

It would be greatly appreciated if an example could be provided based upon –

All Public Folders

 Corporate Contacts

(the public folder I’m searching)

Thanks in advance.
