Changing the file name of an attachment in the body of Outlook ema

[JB]

In Outlook 2000, when in a Rich Text email message, we had the ability to
right-click, choose Properties, and change the Email attachment(s) file name.
Since we've upgraded to Outlook 2003, this feature doesn't work, and our
users want it back. Does anyone know how to enable a feature so that we can
change the attachment(s) name once the attachment(s) is in the body of the
email message?

(We don't want to Save as, change file name & re-attach).
thanks.
