Today the Exchange Team released Rollup 13 for Exchange Server 2007 Service Pack 3 (KB2917522). This update raises Exchange 2007 version number to 8.3.348.2.
· When running ForeFront Protection for Exchange, make sure you disable ForeFront before installing the rollup and re-enable it afterwards, otherwise the Information Store and Transport services may not start. You can disable ForeFront using fscutility /disable and enable it using the fscutility /enable command;
· Rollups are cumulative, i.e. they contain fixes released in earlier update Rollups for the same product level (RTM, SP). This means you don’t need to install previous Rollups during a fresh installation but can start with the latest Rollup package.
