In the Frequent Contacts address book you can display a field labeled
'Last Reference' which I believe shows the date/time when a message was
last sent to the address book entry.

I would like to programmatically access this field & value using the
GroupWise Object API. I have tried using the AddressBookEntry object and
its associated Fields collection but it is not presented when I iterate
through the fields.

Can anyone tell me where this data is stored?

Many thanks in advance,
