office. The sites connect to each other by using a high-speed WAN link. The WAN link has
an average utilization rate of 90 percent during business hours. The domain contains three
domain controllers. The domain controllers are configured as shown in the following table.
The network has an Exchange Server 2010 Service Pack 1 (SPl) organization that contains

• One RAID 1 disk array that has two 73-GB, 10,000-RPM SAS disks for the operating system
Requirements
Business Goals
Contoso has the following general requirements that must be considered for all technology
deployments:
• Minimize costs whenever possible.
• Minimize administrative effort whenever possible.
• Minimize traffic on the WAN link between the offices.
Planned Changes
Contoso acquires a company named Margie’s Travel. Margie’s Travel has 3,000 employees.
Margie’s Travel has the following email infrastructure:
• A call center, where 200 employees work
• UNIX-based email hosts that users access by using POP3 and SMTP
• Three departments that use the SMTP domains of margiestravel.com,
east.margiestravel.com, and blueyonderairlinesxam. Users are assigned only one email
address that uses the SMTP domain of their department
You plan to deploy a new Exchange Server 2010 SP1 organization to Margie’s Travel. The
new email infrastructure must meet the following implementation requirements:
• All employees must have access to their mailbox if a single server fails.
• Call center employees must use windows Internet Explorer 8 to access their mailbox.
• The administration of the Margie’s Travel Exchange organization must be performed by a
dedicated team.
• Call center employees must be prevented from accessing the calendar or journal features of
Outlook Web App.
• All employees who do not work in the call center must have access to all of the Outlook
web App features.
• All email messages sent to recipients outside of Margie’s Travel must have a return address
in the user@margiestravel.com format.
The new email infrastructure for Margie’s Travel must meet the following security
requirements:
• Contoso administrators must be prevented from viewing or modifying the settings of the
mailboxes of Margie’s Travel users.
• All inbound and outbound Internet email to and from the Margie’s Travel domains must be
routed through the Hub Transport servers of Contoso.
• All email messages that contain confidential customer information must be encrypted
automatically while in transit and the recipients of the messages must be prevented from
forwarding them to other users.
Compliance Requirements
Contoso must meet the following compliance requirements:
• Each email message sent by an attorney from the Contoso legal department must be
approved by the manager of the legal department.
• Attorneys must be able to classify email messages as “attorney-client privileged”.
• All messages classified as “attorney-client privileged” must contain a legal disclaimer
automatically.
User Requirements
All users who have a portable computer use Microsoft Outlook 2010 when they work online
and offline. When the users work offline, they must be able to read existing email messages
and create new email messages. Users who have a large mailbox must minimize the amount
of hard disk space used by the mailbox on their portable computer.
