Objective: Designing and planning coexistence and migration
SubObjective: Design and plan for migration of legacy Exchange features

 

Item Number: 70-237.3.1.6
Single Answer, Multiple Choice

 

You are the messaging engineer for TXGlobal Corp. Your organization has two Active Directory forests: TXGlobalForestA and TXGlobalForestB. There is a cross-forest trust relationship between them. Both the forests have an Exchange Server 2003 messaging system. You plan to migrate the messaging system in TXGlobalForestB to Exchange Server 2007 in six months. You also plan to migrate all computers from Microsoft Office 2003 to Microsoft Office 2007 in the same time frame.

 

You need to recommend a solution to ensure users in one forest are able to access free/busy data about users in both the forests for the next six months.

 

What should you recommend?

 

 

  1. Use the global address list (GAL) Synchronization feature in Microsoft Integration Identity Server (MIIS) 2003
  2. Use the Availability service
  3. Use the /EnableLegacyOutlook parameter while installing the Mailbox Server
  4. Use the Microsoft Exchange Server Inter-Organization Replication tool

 

Answer:
D. Use the Microsoft Exchange Server Inter-Organization Replication tool

 

Tutorial:
You should use the Microsoft Exchange Server Inter-Organization Replication tool to ensure users in one forest are able to access free/busy data about users in both the forests. The Microsoft Exchange Server Inter-Organization Replication tool allows sharing of free/busy data between users in a cross-forest environment, where one forest does not have any Exchange 2007 Mailbox servers, or users do not use Outlook 2007 to access their e-mail. In this scenario, neither forest will have Exchange Server 2007 for the next six months. To use the Inter-Organization Replication tool, you must have at least one Exchange 2000 Server or Exchange Server 2003 server in each forest.

 

You should not use the GAL Synchronization feature in MIIS 2003 to ensure that users in one forest are able to access free/busy data about users in both the forests. The GAL Synchronization feature provides users in a forest access to global address list information of both forests. The GAL Synchronization feature does not provide access to free/busy data. The mail recipient information is stored in a GAL for a single forest. You should enable and configure the GAL Synchronization feature in MIIS 2003 if you have a cross-forest environment. This will ensure the GAL in both the forests contains mail recipient information for both forests.

 

You should not use the Availability service to ensure users in one forest are able to access free/busy data about users in both the forests. You should install Exchange Server 2007 in both forests to use the Availability service to enable users in a cross-forest environment to gather free/busy data about users in both the forests. Also, to use the Availability service, users should use Microsoft Office Outlook 2007 client to access their e-mail messages. In this scenario, Exchange Server 2007 will not be deployed for six months. You should use the Microsoft Exchange Server Inter-Organization Replication tool to ensure users in one forest are able to access free/busy data about users in both the forests.

 

You should not use the /EnableLegacyOutlook parameter while installing the Mailbox Server to ensure users in one forest are able to access free/busy data about users in both forests. This parameter is used to create a public folder database on a Mailbox server. To use this parameter, client computers in your messaging system must use Microsoft Office Outlook 2003 or earlier versions. For example, if you want to remove the need for public folder databases in a forest, then you should ensure all client computers in that forest are running Microsoft Office Outlook 2007.
