Um pouco de história do Exchange

Estava a ler o documento An Overview of Microsoft Exchange Server 2007 White Paper, quando descobri esta tabela com todas as datas de lançamento das principais releases do Exchange:



O Exchange completou recentemente o seu 11º aniversário, está a ficar mais velho e melhor!

Quanto à minha experiência pessoal, apesar de ter trabalhado com o defunto MS Mail 3.1, o meu primeiro contacto com o Exchange deu-se já na versão 5.0. Foi amor à primeira vista ;-)

E quanto aos nomes de código das várias versões do exchange? Aqui fica a tabela:

E quanto ao futuro? Bem, neste momento está já a ser desenvolvida a próxima versão, nome de código Exchange "14" (conseguem imaginar porque saltaram a 13?), que deve ver a luz do dia lá para 2010. Mas até lá relaxem e disfrutem das muitas das novas funcionalidades do exchange Server 2007.

[UPDATE]
Enquanto fazia pesquisa para este post, fiquei obviamente intrigado pelo Magma. O David Lemson da Microsoft fez o favor de me esclarecer sobre o assunto:
"Magma was the code-name for the portion of Exchange (the store, mostly) that shipped as part of SharePoint Portal Server 1.0. That product, now MOSS, switched to SQL as their store in the next release. Magma was only built with Exchange 2000 internally, since there is no remaining consumer, it is no longer being built. Magma wasn’t really a product, first because it never shipped except to SPS, and second because it was really just a portion of the store, it didn’t have its own code."
O nome Magma foi inspirado pelo filme Austin Powers.

TechNet Magazine - Edição de Junho 2007

Já está disponível online a edição de Junho da TechNet Magazine.
Desta vez o tema central é a segurança, pelo que poderão lá encontrar alguns artigos bastante interessantes, assinados por autores conceituados, tais como Steve Riley ou Mark Russinovich.
Até agora ainda não encontrei lá nada particular sobre Exchange ou messaging, mas há sempre a rúbrica do Windows PowerShell, que está de algum modo relacionada com a gestão do Exchange Server 2007.
A revista está igualmente disponível para download em formato HTML Help (.chm).

ESEUTIL para copiar ficheiros?

Não há administrador de Exchange que não saiba o que a ferramenta ESEUTIL pode fazer. É bastante útil para desfragmentar as bases de dados do Exchange, recuperando o espaço livre, e também para as reparar em caso de erro.
O que provavelmente muitos não saberão (eu não sabia) é que esta também é a ferramenta indicada para copiar ficheiros muito grandes através da rede, de acordo com a Performance Team da Microsoft.
A sintaxe é bastante simples: eseutil /y /d .

Workflow para Exchange

Um dos muitos feeds que eu acompanho é o Microsoft Download Center, que me permite manter informado dos últimos items disponíveis pra download.
Dois items recentes despertaram a minha atenção:

Afinal não se tratavam de 2 novos produtos, mas sim de produtos descontinuados e que se destinavam ao Exchange Server 2000. Qual a solução para quem quiser desenvolver mecanismos de workflow para o Exchange? Windows Workflow Foundation!

"Microsoft recommends that you migrate applications that use Exchange Workflow and the Collaborative Data Object for Exchange Workflow (CDOWF) to use the Windows Workflow Foundation. Windows Workflow Foundation supplies the programming model, engine, and tools required to quickly build workflow-enabled applications on Microsoft Windows. It consists of a namespace, an in-process workflow engine, and designers for Microsoft Visual Studio 2005. Applications that use Windows Workflow Foundation can be developed and run on Microsoft Windows Vista, Microsoft Windows XP, and the Microsoft Windows Server 2003 family. Windows Workflow Foundation includes support for both system workflow and human workflow across a variety of scenarios, including workflow within line-of-business applications, user interface page flow, document-centric workflow, human workflow, composite workflow for service-oriented applications, business rule–driven workflow, and workflow for systems management.If you have developed applications that are based on the Exchange SDK Workflow Application Template and you require a copy of the installation package for archival purposes, please contact Microsoft Customer Support Services.The Exchange SDK Workflow Application Templates will be supported while Microsoft Exchange Server 2003 support is available."

Update Rollup 2 for Exchange Server 2007 (KB935490)

Quem já fez download do patch do Exchange Server 2007 para corrigir a vulnerabilidade mencionada no post anterior, reparou com certeza que foi direccionado para o Update Rollup 2 for Exchange Server 2007 (KB935490).
Pois é, poucos dias dias depois de ter disponibilizado o Update Rollup 1, eis que surge um novo rollup.
Desenganem-se os que pensam que a Microsoft vai iniciar um novo ciclo de releases de rollups todas as 3 semanas, o principal motivo deste teve a ver com a vulnerabilidade já mencionada.
Esta actualização é cumulativa, o que quer dizer que dispensa a instalação do Update Rollup 1. Para uma lista das correcções incluídas, consultar o respectivo artigo da Knowledge Base: Description of Update Rollup 2 for Exchange 2007.

Aqui fica o link para o respectivo boletim de segurança que contém as informações necessárias para obter os respectivos patches correctivos:
