Insert Item - how to get 'To' field in pop up screen

[susann]

We quite regularly use the Insert Item function in Outlook to attach copies
of email messages we have sent. The emails we attach are stored in various
public folders.

The only problem I have with this is that when the 'Insert Item' screen
appears it only have the columns From, Subject, Received, Categories. It
would be incredibly useful to have the 'To' column there as well. Is it
possible?

Thanks
Susan
