I have two email accounts in Outlook 2003, and as I understand it, they
have to share one inbox and I can have rules that forward them to a
sub-box. No problem.

BUT, when I send email which account shows up in the FROM field? When
they reply, which account address will it grab? I want to control which
is used as I compose emails. This is important so replies go to the
correct box. Make sense? Anyone know how I am to do this?

Thanks.
