For a brief period of time on August 9, 2008, a pre-release version of Update Rollup 4 for Exchange Server 2007 Service Pack 1 (KB952580) was inadvertently made available to Microsoft Update, the Microsoft Update Catalog, and Windows Software Update Services (WSUS) servers for download. While we quickly removed the update from Microsoft Update within a short period of time, some servers using these distribution methods might have detected, downloaded and/or installed this version of the update.
Known issues exist with this pre-release version of Update Rollup 4, including issues with Exchange Web Services (EWS) that creates the potential for a continuous crashing cycle, an uninstall issue where the EWS web.config is reset, and an issue with backup validation. The final release version of Update Rollup 4 will be released in the upcoming weeks, and until then, we recommend that customers who have not already installed Update Rollup 4 wait to do so. If you have already installed Update Rollup 4, we recommend uninstalling it.
The following known issues exist in the pre-release (version 8.1.311.1) of Update Rollup 4 for Exchange server 2007 Service Pack 1 (KB952580). Also included are recommended steps to resolve this for customers who encounter any of the issues.
