-we have a single exchange organization in active directory forest:
nyc.domain.com.
-we have 2-front end servers and 5-backend servers (only users with
user@domain.com gets delivered here)

-we recently acquired a new company that wants to join our exchange
environment
-the acquired company is located in europe and all of it employees
-i want to add 2-front end in europe 3-backend servers to their new domain:
europe.domain.com
-i want all email for domain.uk (user@domain.uk) to point to the eruope
exchange servers. they should not go to the nyc.domain.com exchange
front-end server.

is this possilbe with routing groups for Microsoft Exchange 2003? Thanks.

- Assuming you'll create a separate Routing Group for europe.domain.com
- Run Domainprep in the europe.domain.com AD domain
- Setup Exchange servers in that domain
- Create a new RUS and point it to a DC in the europe domain
- Create Routing Group Connectors to nyc.domain.com and back (RG Connectors
are one-way)
- Create a SMTP Connector for address space * in the Europe Routing Group,
choose local servers as bridgeheads
- Create a Recipient Policy with a filter that can pick up all users who
need the domain.uk email addresses
- Make sure DNS zone for domain.uk exists on a DNS server accessible from
the internet, MX record points to appropriate (A records of) the server(s)
in Europe
- Make sure inbound smtp connectivity exists to those servers (that accept
inbound mail) from the internet. This will involve setting up your firewall
with appropriate NAT & access rules.
