I've a customized Outlook 2003 form where the cc: line is populated by
aggregating the e-mail addresses from the to: from: and prior cc: items.
This is to guarentee that once a person shows up in an e-mail stream they'll
continue to get all related e-mails automatically.

The problem is looks. One individual can show up many times in the cc:
line. Any tricks or tips to make sure e-mail IDs only show up once in the
cc: line, no matter how many times an individual may have received earlier
versions of the e-mail?

Thanks-

Richard
