Multiple Domains Single Exchange Server 1

[mapman04]

Can Exchange host e-mail for two separate network domains but both have the same e-mail domain name. Here's what I need:

Corporate headquarters in US. A subsidiary company in Europe.

The US network domain is named Corp. The European network domain is Europe. I want both domains to use a single exchange server under the corp domain for e-mail. I'm assuming it's just a domain/trust configuration. Is this possible?

Thanks in advance,

Mapman04

You may consider Exchange resource forest scenario.
"A variation of the resource forest scenario is a multiple forest where one forest hosts Exchange. If you have multiple Active Directory forests, how you deploy Exchange depends on the degree of autonomy that you want to maintain between the forests. Companies with business units that require security (forest) boundaries for directory objects, but can share Exchange objects, may choose to deploy Exchange in one of the forests and use it to host mailboxes for the other forests in the company. Because all Exchange resources are contained in a single forest, a single GAL contains all users across all forests."
