In MS Outlook, report all sent-messages that haven't received replies

I send out a lot of emails each day and often fail to keep track of which ones actually get replied to.

Is there a way I can use a VBA script to look at say all the sent messages in the last week, and check if they received replies?

Specifically, a report of the sent email messages that have NOT yet received replies to them from at least one of the addresses they were sent to.

I know a little bit of Excel VBA but I don't know where to start with this one... or if it's even possible.

Ideas?
