General Notes

Note for Exchange 2010 Customers using the Arabic and Hebrew language version: We introduced two new languages with the release of Service Pack 1, Arabic and Hebrew. At present we are working through the process of modifying our installers to incorporate these two languages. Customers running either of the two language versions affected are advised to download and install the English language version of the rollup which contains all of the same fixes.

Note for Forefront users: For those of you running Forefront Security for Exchange, be sure you perform these important steps from the command line in the Forefront directory before and after this rollup's installation process. Without these steps, Exchange services for Information Store and Transport will not start after you apply this update. Before installing the update, disable ForeFront by using this command: fscutility /disable. After installing the update, re-enable ForeFront by running fscutility /enable.
