Hello,

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.

Aleks

Hi,
I am assuming that you are talking about seperate forests and not seperate domains, within a single forest. (I know you said that too :-))
See in this case you are talking about Resource Forest Scenario, which is being used at many larger organizations, smaller organizations do not prefer it due to additional adminstrative overheards of managing 2 or more forests etc. Please refer: http://www.msexchange.org/articles_tutorials/exchange-server-2007/planning-architecture/deploying-exchange-resource-forest-part1.html
Let me know
Thanks

Hello Nitin,

yes you are right, my mistake. I meant seperate forrests. So let me be clear, you have:
Forrest A, with Domain A
Forrest B, with Domain B
Forrest C, with Domain C

The thing is that this company has has 3 different businesses. The people from forrest A are to be isolated from viewing data on the network of Forrest B and Forrest C. but they have to have the same email "xxx@companyname.com"
These 3 different forrests are in 3 differents subnets which automtically seprates the networks from each other. This works great but now the customer wants to implemement a Exchange environment and all employees from all the forrests have to have an email adres with the same company name. So for example:

- Jack from forrest A has to have email address jack@companyname.com
- Jane from forrest B has to have email address jane@companyname.com

What worries me is that these forrests are in different subnets.  Forrest A has subnet ip range 172.22.0.0 and Forrest B has 192.168.1.0
Can i leave these 2 subnets separated like this and create a new exchange forrest with a different subnet, for example ip 192.168.10.x?

Hi,
Yes you can create different subnets and in real life scenarios you will have difffernt subnets only. It is about allowing routing between these subnet using some Router.
And on same email address, just refer to the URL I gave, you will be on track
Cheers
