621 Before You Begin Before you perform the procedure in this topic, be aware that the procedure contains information about editing the registry. Caution: Incorrectly editing the registry can cause serious problems that may require you to reinstall your operating system. Problems resulting from editing the registry incorrectly may not be able to be resolved. Before editing the registry, back up any valuable data. Procedure To enable an SMTP virtual server to accept message extended properties sent anonymously 1. Start Registry Editor. 2. Navigate to HKLM\SYSTEM\CurrentControlSet\Services\SMTPSVC\XEXCH50. 3. Right-click XEXCH50, select New, and then click Key. 622 4. Type the number of the SMTP virtual server instance as the key value. For example, the default SMTP virtual server instance is 1, while the second SMTP virtual server created on a server is 2. 5. Right-click the key you just created, point to New, and click DWORD Value. 6. In the details pane, type Exch50AuthCheckEnabled for the value name. By default, the value data is 0, which indicates that the extended message properties are transmitted when mail is sent anonymously. For More Information For information about how to edit the registry, see Microsoft Knowledge Base article 256986, "Description of the Microsoft Windows Registry" (http://go.microsoft.com/fwlink/?linkid=3052&kbid=256986). Consolidating Sites in Exchange 2003 Site consolidation entails moving Microsoft® Exchange out of remote sites and into a larger central site and allowing users in remote offices to access their mailboxes and public folders over the network. The main 623 justifications for site consolidation are to make the Exchange Server 2003 topology simpler and to make Exchange more cost-effective to administer. If your organization contains servers running Exchange Server 5.5, the site consolidation process requires additional tools to ensure that mailboxes, distribution lists, recipients, and public folders are moved properly and with the least disruption in service. The goal is to ensure that after users and Exchange data are moved to the central site, mail continues to flow properly. There are several new tools and features in Exchange 2003 Service Pack 1 (SP1) that help with the site consolidation process. This topic discusses the steps you should take to ensure that your environment is ready for site consolidation. After you perform these steps, you can use the Exchange Server Deployment Tools to begin the site consolidation process. For more information about planning your Exchange 2003 site consolidation, see "Planning for Site Consolidation" in the guide Planning an Exchange Server 2003 Messaging System (http://go.microsoft.com/fwlink/?linkid=21766). 624 Exchange Server Deployment Tools For complete instructions about how to consolidate your sites, download the latest Exchange Server Deployment Tools, available from the Downloads for Exchange 2003 Web site (http://go.microsoft.com/fwlink/?linkid=25097). The SP1 version of the Exchange Server Deployment Tools contains information and tools that help you during your site consolidation process. The procedures referenced in this topic guide you through the processes you must complete before you use the Exchange Server Deployment Tools. Site Consolidation Tools During site consolidation, many mailboxes, distribution lists, contacts, and public folders may need to be moved across administrative groups. In addition, the legacy Exchange distinguished name (legacyExchangeDN) for an object changes after the object moves across administrative groups, which affects the services that depend on this attribute. The following Exchange 2003 SP1 features and tools address these concerns: Move Mailbox Wizard in Exchange 2003 SP1 625 Exchange Profile Update tool (Exprofre.exe) Public Folder Migration tool (PFMigrate) Object Rehome tool Move Mailbox Wizard in Exchange 2003 SP1 The Exchange 2003 SP1 version of the Move Mailbox Wizard gives you the option to move mailboxes across administrative groups. If your Exchange organization is in mixed mode, by default, Exchange 2003 displays one administrative group and one routing group for each Exchange 5.5 site. Previous to Exchange 2003 SP1, if your organization contained Exchange 5.5 servers, you could move mailboxes only within the same administrative group. This limitation meant that you could not easily consolidate remote Exchange 5.5 sites into a central Exchange site. In Exchange 2003 SP1, you can move mailboxes across administrative groups by using either the Move Mailbox Wizard in Exchange System Manager or the Exchange Task Wizard in Active Directory Users and Computers. 626 Important: When moving mailboxes from the remote site to the central site during your site consolidation process, it is recommended that you have a minimum bandwidth speed of 256 kilobits per second (Kbps). Mailbox moves may fail if the bandwidth speed is too slow. Also, at slow bandwidth speeds, connections to servers in the remote site might be blocked due to the network traffic that is generated by moving mailboxes. Moving Exchange Mailboxes After backing up your mailbox data, you can move your mailboxes across administrative groups. For more information about moving your mailboxes, see the SP1 version of the Exchange Server Deployment Tools. Exchange Profile Update Tool The Exchange Profile Update tool (Exprofre.exe) is a stand-alone executable file that automatically updates users' Microsoft Office Outlook® profiles, thereby allowing users to log onto their relocated mailboxes after the mailboxes have been moved across Exchange organizations or administrative groups. To reflect the new information, 627 you must run Exprofre.exe on each client computer to update the default Outlook profile. It is recommended that you use a logon script to run this tool. Download the Exchange Profile Update tool from the Downloads for Exchange 2003 Web site (http://go.microsoft.com/fwlink/?linkid=25097). The Exchange Profile Update tool is supported when used in conjunction with the following operating systems and applications: Microsoft Windows® 2000 (all editions) Microsoft Windows XP (all editions) Windows Server™ 2003 (all editions) Outlook 2003 and all earlier versions of Outlook Note: Exprofre.exe does not run if Outlook or another MAPI application is running on a client computer. A warning appears stating that Outlook must be closed to run the tool. 628 Exprofre.exe uses information from Microsoft Active Directory® directory services and the current default Outlook profiles to perform the following steps: Back up the default profile Look for an X.500 e-mail address that indicates that the mailbox has been moved. Update the default profile with the new user and server properties Reconfigure the default profile with the new RPC/HTTP front-end server name Clear the user's nickname file If the version of Outlook is earlier than Outlook 2003, delete or rename the offline folder store (.ost) file Delete or rename the Favorites (.fav or .xml) file 629 Note: Exprofre.exe updates only the default profile. Exprofre.exe does not create new profiles; it only modifies existing profiles. If the tool does not complete successfully, Exprofre.exe creates a backup profile before it modifies the default profile. The backup profile name consists of the old profile name with "backup" added to the end. For example, if the default profile name is "Ted Bremer," the backup profile name is "Ted Bremer backup." If it is necessary to revert to the backup profile, you must ensure that any file name extensions that have been changed are changed back to their original extension and, if necessary, that the file name matches the backup profile name. For example, when the tool creates the backup profile, it renames Ted Bremer's Favorites file to "Ted Bremer.exprofre." To revert to Ted Bremer's backup profile, you must change the extension of the Favorites file back to .fav and the name of the file to "Ted Bremer backup.fav" to match the backup profile name. Using the Exchange Profile Update Tool Run Exprofre.exe after you move mailboxes from one Exchange organization to another or from one administrative group to another. You can use a logon script or group policy to run the tool for Outlook users. 630 Note: It is recommended that you use a logon script to run Exprofre.exe so that users' Outlook profiles are updated when they first log on after the mailbox move. For sample commands, see "Sample Command for Moves Across Exchange Organizations" and "Sample Command for Moves Across Administrative Groups" later in this topic. Table 1 describes the options that are available whether you run exprofre.exe from a command prompt or from within a script, such as from the following script example: exprofre.exe [/?] [/targetgc=<global catalog server>] [/logfile=<path\filename>] [/v] [/f] [/a] [/r] [/o] [/p=<RPC over HTTP Proxy server>] [/n] [/s] [/q] Table 1 Exprofre.exe command options Command option Description /?
