Actualização de documento: "The Role of Groups..."

O documento The Role of Groups and Access Control Lists in Microsoft Exchange 2000 Server Deployment foi recentemente actualizado.
É uma leitura bastante interessante para quem ainda utiliza Exchange 5.5 e está a pensar numa actualização para a versão 2003. Entre outras coisas, o documento faz uma analogia entre as Distribution Lists e os grupos de distribuição do Windows 200x, e tece algumas considerações sobre migrações e actualizações.

Já agora, lembrem-se que se estão a pensar numa migração de Exchange 5.5 para uma nova floresta/organização , não é possível migrar as Distribution Lists utilizando apenas as ferramentas de migração da Microsoft. Para superar esta situação, criei um pequeno script que disponibilizei publicamente. O script e as instruções de utilização estão disponíveis neste artigo: Inter-Org Distribution List Migration.

Exchange SP2 CTP disponível a 19-Agosto

De acordo com úm post do Harold Wong e de notícia publicada pela Mary Jo Foley, a Microsoft vai disponibilizar uma Community Technology Preview (CTP) do Service Pack 2 para o Exchange Server 2003 a 19 de Agosto.
A versão CTP funciona como uma pré-beta e tem algumas limitações:

"Please be aware that CTP releases of any product will not display the stability of a shipped Microsoft product. Customers may encounter problems with Exchange Server 2003 SP2 that could possibly result in a loss or destruction of data. Some of the mobility features contained in this CTP download are not yet available for testing, pending availability of Windows Mobile 5.0 devices that have the Messaging & Security Feature Pack installed. Those devices will be available later in 2005 and 2006. Also some of the security features in SP2 are only available when used with Outlook 2003 SP2 which will not release until later in 2005. This build is available only in English."

Pode começar a contagem decrescente. Até já existe um link reservado.

Netcabo actualiza Exchange para a versão 2003

Foi com agrado que recebi a notícia que o ISP português Netcabo concluiu a actualização da sua plataforma de correio electrónico para a versão Exchange Server 2003.
Há já algum tempo que os front-ends haviam sido actualizados (notou-se uma pequena melhoria gráfica, mas a versão do OWA era à mesma a 2000), mas só agora com a actualização dos back-ends, os utilizadores podem disfrutar das novas funcionalidades e melhorias a nível gráfico introduzidas com o Exchange 2003.
A propósito das versões de front-ends e back-ends, aqui fica uma pequena tabela com as configurações suportadas (disponível no artigo da Knowledge Base Q829057):

Microsoft recruta 2 ex-IBM

O mercado IT é agressivo por natureza. Depois da saída polémica de Kai-Fu Lee da Microsoft para o seu rival Google, agora é a própria Microsoft que resolveu contratar 2 ex-funcionários da IBM: Julio Estrada e Bob Congdon.
Os dois sujeitos estavam envolvidos no desenvolvimento do Lotus Notes, pelo que é mais ou menos óbvia a sua integração na equipa do Microsoft Exchange.

Nova versão do ExBPA (v2.1a)

A Microsoft disponibilizou uma nova actualização da ferramenta Exchange Best Practices Analyzer (ExBPA). A nova versão, 2.1.7599.4 contém correcções a alguns bugs e está disponível para download aqui.

O spam não compensa - Parte II

Depois de há alguns dias o spammer mais famoso da Rússia ter aparecido morto, chega-nos agora a notícia que um dos "reis do spam", Scott Richter aceitou pagar 7 milhões de dólares, num acordo à margem do julgamento de que era alvo.
A beneficiária do montante, a Microsoft, vai empregar 6 milhões em actividades contra o crime (sim, o spam é crime!) na internet.
Só cá em Portugal é que parece que os spammers continuam impunes. Também, com as leis relativamente permissivas e a qualidade do nosso sistema judicial, não é de admirar.

Ferramentas de Exchange: novas versões

Algumas ferramentas do Exchange 2003 foram recentemente actualizadas. Se é daqueles que gosta de ter sempre a última versão, aqui ficam os links:

Spam em português

Sim, é verdade, existe muito spam em português, isso não é novidade. Pessoalmente, acho que a lesgislação comunitária é muito permissiva nesse aspecto.
Mas não é sobre isso que vos quero falar, é antes sobre um novo site - www.eliminarspam.com - que contém variada informção de combate ao spam em português. Infelizmente não existe muita informação técnica em português, pelo que é de louvar estas iniciativas.
A informação disponível no site ainda não é muita, mas já é um começo.

Limites de mensagens e links lentos

O Exchange Server 2003 tem algumas características que o tornam particularmente adequado para cenários de "branch offices" ligados a um escritório central, nomeadamente a possibilidade de utilizar o modo offline (em conjunto com o Outlook 2003) e uma melhor compressão das comunicações.
Uma das grandes preocupações de quem é responsável por links com largura de banda reduzida é a limitação do tráfego que atravessa esse link. É por isso de todo conveniente que se limitem os tamanhos máximos das mensagens que os utilizadores remotos podem enviar ou receber.
No entanto, um dos grandes problemas do Exchange foi que não existia maneira de garantir a aplicação das políticas de dimensão das mensagens no lado do cliente. Vejamos, se um cliente que tenha um limite de envio de 2MBytes enviar uma mensagem de 10MBytes, essa mensagem vai ser enviada do seu Outlook até ao servidor central, atravessando o link, e só aí vai ser rejeitada.
Esta limitação foi recentemente corrigida com a disponibilização de 2 hotfixes, um para o Exchange, outro para o Outlook 2003.
