You are the enterprise administrator for an Exchange Server 2010 organization. All users run
Microsoft Office Outlook 2010. You are designing a sharing solution for your organization and a
partner organization. The partner organization also uses Exchange Server 2010. You need to
recommend a strategy for sharing information with the partner organization to meet the following
requirements:
• Provide cross-organizational access to user contacts
• Provide cross-organizational access to free\busy information

Creating cross-forest trusts
Explanation:
Information workers frequently need to collaborate with external recipients, vendors, partners, and
customers and share their free/busy (also known as calendar availability) and contact information.
Federation in Microsoft Exchange Server 2010 helps with these collaboration efforts. Federation
refers to the underlying trust infrastructure that supports federated delegation, an easy method for
users to share calendar and contact information with recipients in other external federated
organizations. To learn more about federated delegation, see Understanding Federated Delegation.
Example:
Two Exchange organizations, Contoso, Ltd. and Fabrikam, Inc., want their users to be able to share
free/busy information with each other. Each organization creates a federation trust with the
Microsoft Federation Gateway and configures its account namespace to include the domain used for
its user’s e-mail address domain.
Contoso employees use one of the following e-mail address domains:
contoso.com, contoso.co.uk, or contoso.ca. Fabrikam employees use one of the following e-mail
address domains: fabrikam.com, fabrikam.org, or fabrikam.net. Both organizations make sure that
all accepted e-mail domains are included in the account namespace for their federation trust with
the Microsoft Federation Gateway. Rather than requiring a complex Active Directory forest or
domain trust configuration between the two organizations, both organizations configure an
organization relationship with each other to enable free/busy sharing.
The following figure illustrates the federation configuration between Contoso, Ltd. and Fabrikam,
Inc.
