The Exchange CXP team has released Update Rollup 2 for Exchange Server 2007 Service Pack 2.
In addition to bug fixes reported by customers we have added new rules to the Exchange Best Practices Analyzer to check the health of your system. Starting this rollup, customers who wish to deploy the new BPA health rules to a server with no internet connection can do so by downloading the installing the update rollup on the server. Until Exchange Server 2007 Service Pack 2, updates to the BPA rules were available only via the web which meant customers wanting to deploy the new health check rules to servers not connected to the internet would have had to copy over the XML files manually. In Exchange 2007 SP2, we implemented a work item which allows us to ship updates to the BPA health check rules via the rollup and as well as via the traditional web based channel. More on this via a blog post in the near future.
