Is it possible to change the icon used for an opened MailItem? I have a
criteria that I would like to classify e-mails using a custom Outlook field.
I would like to change the icon based on this classification. Is this at all
possible in Outlook 2003 sp2?

The only folder I truley care about showing this icon would be the Sent
folder, if it matters.

I would like to use VSTO with VS 2005.

Thank you,
DG
