Exchange CXP team has released Update Rollup 2 for Exchange Server 2007 Service Pack 2 (KB 972076) to the download center.
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.
KBA 972076 lists all the fixes included in this rollup. Here are some of the product improvements and critical bug fixes we'd like to call out:
KB 972705: This one is for all the IT pros and anyone who has ever had to explain abnormal database size/log file growth in a short period of time. We have added three new registry entries to help speed up troubleshooting the issue:
More information on the values to set in the above registry keys is documented in KB 972705.
KB 975404: Accepting meeting requests sent via an application using CDO like Blackberry devices sometimes results in rendering an embedded message attached to the meeting request inaccessible.
KB 976137: We have made a change to the behavior of the Unified Messaging Auto attendant when it plays the greeting for callers on a holiday. Currently when callers call on a holiday, they hear the non-business hours greeting followed by the holiday greeting. In this rollup we have made a change so that the callers calling on a holiday will only hear the holiday greeting. If your greetings are configured such that they would make sense to callers calling on a holiday only if they hear both the non-business hours greeting and the holiday greeting, then you need to re-configure them when you install this update rollup.
KB 971177: Another change in the UM Auto Attendants configuration in the Exchange Management Console. It is now aware if your time zone follows Daylight Saving Time.
KB 975165: In an environment using self-signed certificates and CAS-CAS proxying, Exchange Web Services requests proxied may start failing after the Availability Service has made a proxy request.
A bug where the OWA Virtual Directory cannot be accessed via the Exchange Management Console in an environment coexisting with Exchange 2010 if the Exchange 2007 server was upgraded from Exchange 2007 SP1 to SP2.
