With the launch of Exchange 2010, we have introduced a new way to manage the set of languages available for Exchange.
In previous versions of Exchange, you had one server language per DVD. In Exchange 2010, we have changed to a new language neutral design. This allows us to release all available languages in a single DVD. We can also add and update additional languages over the lifetime of the product. This model also allows us to easily update the translation quality over the lifetime of the product. We are no longer dependent on component updates or service pack deployments.
We provide this flexibility through the use of a language pack bundle. The Exchange 2010 RTM DVD contains our initial version of this bundle. Exchange Setup will install this bundle from the DVD, from a network share, or recommend you to download the most up to date version of the bundle if your server has internet access. Since Exchange 2010 RTM, we have released an updated build of the bundle, available from here. Our recommendation is that all customers deploy this updated bundle as it contains both additional client languages, as well as translation improvements for all the languages. An up to date list of supported languages can be found in Exchange 2010 Language Support. Going forward, we do expect to release updated language pack bundles to improve quality and add additional languages.
The language bundle is delivered as a single downloadable file which includes all localized resources for the server— including Exchange Management Console (EMC) and client (OWA & ECP) interfaces within Exchange. To get a localized experience in EMC, ECP and OWA, you need to install the language pack. Listed below are three scenarios that we would like to call out and provide guidance around them with regards to language pack installation.
