A customer of mine has 3 different forrests in his company with 3 different subnets:
Domain A with IP 172.22.0.0
Domain B with 192.168.0.0
Domain C with 10.10.10.0
He now wants to implement an Exchange 2007 environment (he has no exchange at this moment) as a new forrest and call it Domain "D" with for example ip range 192.168.8.0.
The goal is to let the users from each domain A,B and C connect to this new domain D with a trust between the domains. The users then could configure their outlook with email adres xxx@domainD.com (example)
Is this scenario possible to do? And advice would be appreciated.
Thanks in advance.
