Please Help!

I am setting up a new Exchange 2003 server in our Active
Directory domain which is lfc.com. This is our internal
domain name which is invalid to the outside world. Our
valid outside domain is Laborcorp.com which has an email
server that is hosted by our Domain people. They host our
200 and something email addresses on a server called
mail.laborcorp.com which has a MX record from
laborcorp.com. This is where my question comes into play.
The new Exchange Server will be on the internal domain
lfc.com but will only be hosting 30 of the 200 names from
the main email server. I need to know what I need to do
(DNS entries, Outlook Web Access website name because it
can't be exchange.lfc.com(invalid domain) forwards
etc...) to get this to work. I have a DNS server for
lfc.com and also laborcorp.com let me know if you can,
what the changes should be and where. Exchange server
name is exchange.lfc.com

Thank you for any help

If I understand correctly, you want to have most of your mailboxes on a
remote server with a handful of mailboxes on your email server. You want
these 30 users to have the same email address of laborcorp.com just like the
other 200 mailboxes.

Thus you want to setup domain sharing. Check out these articles:
