Exchange Server Error Code Look-up
A Microsoft disponibilizou uma versão actualizada (v6.0.4011.0) da ferramenta Exchange Server Error Code Look-up.
Overview
Use the Error Code Lookup tool to determine error values from decimal and hexadecimal error codes in Microsoft Windows® operating systems. The tool can look up one or more values at a time. All values on the command line will be looked up in Exchange’s internal tables and presented to you. If available, informational data associated with the value or values will also be shown.
Aqui ficam 2 exemplos do output desta ferramenta:
C:\temp\Err>err 0x8004010f
# for hex 0x8004010f / decimal -2147221233 :
ecNotFound ec.h
ecAttachNotFound ec.h
ecUnknownRecip ec.h
ecPropNotExistent ec.h
MAPI_E_NOT_FOUND mapicode.h
# 5 matches found for "0x8004010f"
C:\temp\Err>Err.exe -528
# for decimal -528 / hex 0xfffffdf0 :
JET_errMissingLogFile esent98.h
# /* Current log file missing */
# 1 matches found for "-528"

Outlook 2007 demos
A Microsoft disponibilizou algumas demos de Outlook 2007. Passados estes meses desde que comecei a utilizar o Outlook 2007, ainda há tanto para aprender!
- Work with SharePoint calendars: Multiple calendars giving you multiple headaches? Stop juggling back and forth and start seeing your calendars all together — in Outlook 2007. When you link your calendar from a Microsoft Windows SharePoint Services 3.0 site to Outlook 2007, you can view and work with the SharePoint calendar right alongside your Outlook calendar. When you make changes in one calendar, the two calendars are synchronized automatically. You can overlay the calendars to make viewing your complete schedule even easier. You can download the demo here any time you like.
- Stay on top of things with Outlook flags: Don't play catch-up — let Outlook flags help you keep up. Flags are colorful reminders for items you need to follow up on, whether tasks, messages, or contacts. Outlook 2007 offers several options for setting flags to complement the way you work. Flags can give you pop-up reminders and they also appear in the To-Do Bar, where you can easily see what actions you need to take each day. The demo shows you how to get started using flags and stay on top of your job. You can download the demo here any time you like.
- Add creativity to your e-mail: You can make your e-mail messages stand out with a few touches from the tools in Outlook 2007. Go from plain white to exciting with eye-catching features like page colors and textures, shading styles, and shapes. You can apply WordArt styles like shadows or 3-D, as well as highlighting and font colors. While you experiment with various graphic effects, you'll see instant previews of your choices in the e-mail message. Watch the demo for quick tips on adding fresh looks to your e-mail! You can download the demo here any time you like.
- 3 ways to share your Outlook Calendar with others: Sharing calendars can make it easier to collaborate with people both inside and outside your company. This demo shows you three ways that Outlook 2007 offers for sharing your calendar. If your company uses Microsoft Exchange Server, you can share your calendar within the organization by using that feature. You can also send a snapshot of your calendar in e-mail to people outside your company. And you can publish your calendar on the Microsoft Office Online Web site and restrict how much detail is shown and who can access it. You can download the demo here any time you like.
- Take inches off your workspace with the updated Navigation Pane: Are you using the Outlook 2007 Navigation Pane as your communications launching pad — where you can get to your most important folders and views with just a click or two? This demo shows you how to change the size of the pane to free up more space, customize the buttons and icons so you see what you want first, and arrange the folders for your convenience. You'll also see how easily you can change the organization whenever you want. Watch the demo and see how to make the Navigation Pane work better for you. You can download the demo here any time you like.

Update Rollup 2 for Exchange Server 2007 SP1 (KB948016)
O Update Rollup 2 for Exchange Server 2007 Service Pack 1 (KB948016) está disponível para download.
Overview
Update Rollup 2 for Exchange Server 2007 Service Pack 1 (SP1) resolves issues that were found in Exchange Server 2007 SP1 since the software was released. This update rollup is highly recommended for all Exchange Server 2007 SP1 customers.
For a list of changes that are included in this update rollup, see KB948016.
This update rollup does not apply to Exchange Server 2007 Release To Manufacturing (RTM). For a list of update rollups applicable to Exchange Server 2007 RTM, refer to the section Update rollups for Exchange Server 2007 RTM in the Knowledge Base article KB937052.
This is a cumulative update rollup and replaces the following:
- KB945684 Update Rollup 1 for Exchange Server 2007 Service Pack 1 (KB945684)
System Requirements
- Supported Operating Systems: Windows Server 2003 R2 (32-Bit x86); Windows Server 2003 R2 x64 editions; Windows Server 2003 Service Pack 2; Windows Server 2003 Service Pack 2 x64 Edition; Windows Server 2008; Windows Vista; Windows XP Service Pack 2
- Exchange Server 2007 SP1 must be installed prior to installing this update rollup.
- This update rollup cannot be installed if you are using Exchange Server 2007 RTM.
- Any Interim Updates for Exchange Server 2007 must be uninstalled prior to installing this update rollup.
- 32-bit editions of Windows Server 2003 with SP2, Windows Server 2003 R2 with SP2, Windows Server 2008, Windows Vista and Windows XP with SP2 are only supported for Exchange Server 2007 management tools.
Exchange Server 2007 Management Tools (32-Bit)
Embora o Exchange Server 2007 só seja suportado em plataformas de 64 bit, isso não quer dizer que não possa ser gerido a partir de sistemas operativos de 32 bit (incluindo Vista!). Para tal, é apenas necessário utilizar as Microsoft Exchange Server 2007 Management Tools (32-Bit), que foram recentemente actualizadas para a versão 685.25.
Brief Description
Exchange Server 2007 is a native 64-bit application that includes 64-bit management tools. You can use the management tools to administer your Exchange Server environment remotely. If the remote computer is running a 32-bit operating system, you will need to download the 32-bit management tools.
Overview
The Exchange management tools include the Exchange Management Console, the Exchange Management Shell, the Exchange Help file, the Microsoft Exchange Best Practices Analyzer Tool, and the Exchange Troubleshooting Assistant Tool.
The new Exchange Management Console (formerly named Exchange System Manager) provides Exchange administrators with a graphical user interface (GUI) to manage the configuration of Microsoft Exchange Server 2007 organizations. For more information about the improvements to the Exchange Management Console, see New Administration Functionality in the Exchange Management Console.
The Exchange Management Shell is a new Exchange-specific command-line interface based on Microsoft Windows PowerShell, formerly codenamed “Monad”. You can use the Exchange Management Shell to run a single command or a series of multiple commands for managing your Exchange Server 2007 servers and objects. For more information about the Exchange Management Shell, see Using the Exchange Management Shell.

You cannot resume setup by performing the action "BuildtoBuildUpgrade"
Recentemente tomei 2 importantes decisões no que respeita ao meu ambiente de testes:
- Mover todas as VMs para Hyper-V;
- Instalar o Exchange 2007 SP1.
A transição para Hyper-V é relativamente simples:
- Remover as VM Additions;
- Criar uma nova VM em Hyper-V VM, utilizando o VHD prévio.
Os problemas começaram quando iniciei a instalação do Exchange Server 2007 Service Pack 1. Ao lançar o Setup, e após a verificação dos pré-requisitos, recebi um aviso que deveria primeiro instalar o .NET Framework 2.0 SP1 (como pude esquecer-me das minhas próprias recomendações?), pelo que interrompi o processo.
Instalado o referido update, retomei o setup, mas desta vez fui presenteado com o seguinte erro:
Setup previously failed while performing the action "install". You cannot resume setup by performing the action "BuildtoBuildUpgrade"
O artigo KB947281 da Knowledge Base da Microsoft descreve este problema e apresenta uma solução. Infelizmente, o artigo está um pouco incompleto. A solução descrita passa por apagar os valores Watermark e Action que poderão estar numa destas chaves de Registry:
- HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Exchange\v8.0\ClientAccessRole
- HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Exchange\v8.0\HubTransportRole
- HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Exchange\v8.0\MailboxRole
No meu caso particular, para ultrapassar a situação, os valores Watermark e Action encontravam-se na chave HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Exchange\v8.0\UnifiedMessagingRole.
A solução completa deverá ser, portanto, a remoção dos valores Watermark e Action, que poderão estar em qualquer uma destas chaves:

Visio - Exchange Server Connector
Está disponível para download o Visio - Exchange Server Connector.
Brief Description
This Microsoft Office Visio 2007 Connector is an add-in for Microsoft Office Visio 2007 that you can use to diagram a Microsoft Exchange Server site topology, including sites, servers, and connections for an organization.
Overview
Although Exchange Management are invaluable tools for managing, monitoring and administer networks, computers, services, and other system components. It does not provide a graphical view of user mailbox details. The administrator has to sift through a tree view and use embedded data to figure out the details
Microsoft Management Console (MMC) hosts administrative tools that you can use to administer networks, computers, services, and other system components. Exchange Management Console and Exchange Management Shell are used to administer and configure specific settings for Mailbox servers and create and manage Mailbox objects.
The Mailbox server role hosts mailbox databases, which contain users' mailboxes. If you plan to host user mailboxes or public folders, or both, the Mailbox server role is required.
Administrators have to sift through a tree view to view the members of the Distribution group in an organization unit.
The Microsoft Office Visio 2007 Connector makes it easy for Exchange administrators to visualize, explore, and communicate complex information. Instead of viewing single user data at a time, administrators can create data-connected Visio diagrams that display data at a glance and dramatically increase productivity.
The Microsoft Office Visio 2007 Connector is an add-in for Microsoft Office Visio 2007 that you can use to diagram a Microsoft Exchange Server site topology, including sites, servers, and connections for an organization.
