Keeping trace of answers

[zungiu]

Hello everyboby,

I need a program (or outlook 2k3 tool) that can help me with outgoing
and incoming emails
The goal is keeping under control the situation of emails sent and
answers received, in order to send quick reminder to those who didn't
answer.
I have in mind something like a panel where I can easily find out which
messages are still not answered, it would be nice if it could treat
separately emails sent to a specific recipient but with with different
subjects, so that I can follow the history of each subject

Thanks to all.
