Exchange 2003 em Windows x64? Nem pensar!

Recentemente, estava eu num cliente a implementar uma infraestrutura de IT - AD, Exchange, SQL, etc. - quando me deparei com um problema inultrapassável. Os servidores eram recentes e suportavam Windows x64, por isso a decisão lógica foi a de instalar esta versão do Windows Server 2003.
Quando chegou a altura de instalar o Exchange Server 2003, começaram os problemas. A parte de Forestprep e Domainprep correram bem, mas quando lancei o setup do Exchange, fui confrontado com um aviso que o ASP.NET não estava instalado.
Após alguma pesquisa no Google, descobri finalmente que esta configuração não é suportada (bolas, já devia saber isto!).
De facto, o Exchange 2003 corre e é suportado em hardware de 64 bits, desde que o sistema operativo instalado seja de 32 bits! Foi a solução seguida.

Exchange e Outlook dominam o mercado do correio electrónico

De acordo com um estudo efectuado pelo Radicati Group, o Microsoft Exchange Server e o Microsoft Outlook são os campeões do mercado do correio electrónico.

The Radicati Group, Inc.’s latest study, “Microsoft Exchange and Outlook Analysis, 2006-2010,” provides an in-depth analysis of current and forecasted MS Exchange installed base, with extensive breakouts by version, business size and region. According to the report, Microsoft Exchange currently commands a 31% installed base market share and a 52% revenue market share of the corporate insourced messaging software market. The next version of Exchange, called Exchange 2007, is expected to be released in early 2007. Microsoft is also currently beta testing a hosted e-mail service called Office Live.

Microsoft has aggressively expanded its reach into the hosted e-mail market since 2003, and we expect that Microsoft’s revenue in this market will grow at an average annual rate of 25% over the next four years.

Microsoft leads the e-mail client market with Outlook, Outlook Express and Outlook Web Access. Uptake for Outlook Mobile, the company’s e-mail client for mobile devices has also been strong, due to increased demand for smartphones.

Standalone Device Emulator 1.0

Finalmente! A Microsoft decidiu lançar uma versão standalone do emulador de dispositivos móveis (smartphone e pocketpc). Antes o emulador estava apenas disponível com a instalação do Visual Studio, embora houvesse uma solução/workaround que não requeria a suite de desenvolvimento da Microsoft (Standalone Emulator).
Bem, o que é certo é que agora já existe a versão oficial standalone. E vem acompanhada com imagens do Windows Mobile 5.0 com o Messaging and Security Feature Pack, o que quer dizer que podemos simular as últimas funcionalidades do Exchange Server SP2: DirectPush e Remote Wipe.
O emulador está disponível neste link e, já agora, aqui ficam umas imagens do seu aspecto.


P.S. À data deste post, a página onde se pode descarregar o emulador tem uma gralha no título ;-)

A Internet Security Systems (ISS) acredita que nos tempos mais próximos poderá surgir um worm que explore a vulnerabilidade descrita no boletim de segurança MS06-019 e que afectará os sistemas baseados em Exchange Server em todo o Mundo. De acordo com a equipa X-Force da ISS:

"Testing done by X-Force confirms denial of service of the Exchange Server is easily achieved with no user interaction and is not mitigated by firewall best practices.
Further analysis of this issue reveals that code execution is possible, but difficult to obtain. However, with the high profile of Microsoft Exchange as a target and the nature in which it is typically deployed, we expect to see active exploitation of this issue in the wild with the possibility of a worm."

Aceitem este conselho, apliquem o patch o mais depressa possível.

Leitura de fim-de-semana

Devido à não publicação desta rúbrica na semana passada, a lista de hoje será anormalmente extensa. Se não tiverem tempo de ler tudo, vejam ao menos o primeiro :-)

Exchange & Office 2007 Roadshow


Andava eu pelos grupos de discussão técnicos da Microsoft, quando li um post do David Figueiredo muito interessante. A Windows IT Pro Magazine em colaboração com a Microsoft está a organizar uma conferência de 1 dia sobre Exchange & Office 2007.

"Get the facts about deploying Exchange & Office 2007 in one information-packed day. Independent Exchange and Office experts will present practical, real-world information in three tracks -- Exchange 12 for the IT Pro, Delivering Better Inbox Value, and The Business Value of Office 2007. Each presentation will end with a question-and-answer session. You'll come away from the Get Ready for Exchange & Office 2007 Roadshow with a clear understanding of how to implement a best-practices migration to Exchange Server 2007, how to use Exchange Server 2007's new capabilities to improve your messaging environment, and how you and your end users can get the most out of Office 2007."

Este roadshow ocorrerá no Centro de Congressos de Lisboa (antiga FIL) no próximo dia 30 de Maio. O registo é grátis e dá ainda direito a uma assinatura digital da revista Windows IT Pro durante 6 meses. Aqui fica o link para o site oficial do evento:

Actualização de ferramentas de Exchange

A Microsoft voltou a realizar pequenas actualizações nalgumas ferramentas de Exchange. Aqui fica a lista:

Documentos de Exchange

A Microsoft está a realizar um esforço no sentido de manter as versões online dos documentos sincronizadas com as versões disponíveis para download.
O último documento documento que passou por este processo foi Exchange Server 2003 RPC over HTTP Deployment Scenarios.
Foi também o caso dos documentos que eu referi num post anterior, Novos documentos de Exchange (?).

E o nome oficial do Exchange "12" é... Exchange 2007

De volta das minhas repousantes férias, deparei-me com esta notícia "bombástica". O nome oficial da próxima versão do Exchange será Exchange Server 2007.
Duh! Mas será que não poderia ser mais óbvio? Senão vejamos, o nome de código da versão presentemente em desenvolvimento é Exchange "12" e a razão para o "12" foi para alinhar com a versão do Office. Ora, dado que o nome oficial do Office há muito que é conhecido, Office 2007, não faria sentido que o Exchange tivesse agora um nome diferente.

E por falar em nomes oficiais, também o Monad foi rebaptizado: PowerShell! Vejam também os links:
