Redirected mail does not show other recipients

I am using Outlook 2003 and have created a rule to redirect mail from one
address to another. The redirects work fine, however, these emails do not
show other recipients (To or Cc) - which I obviously want to see - and also
when replying it does no good to use "reply all". I do not use "forwarding",
since that option doesn't show me the original sender (forwarded emails come
from my own address to which mail was originally sent). Any ideas?
