Exchange 2010 Language Support

Applies to: Exchange Server 2010

Topic Last Modified: 2009-12-09

Microsoft Exchange Server 2010 has enhanced language support for both servers and clients. This topic provides information about language packs, the language selection options available in Setup, and the specific languages that are supported for both servers and clients in Exchange 2010.

Other topics in this section include:

An Exchange 2010 language pack contains the necessary resources for a supported Exchange language. Language packs can be installed during installation of Exchange 2010 or after Exchange 2010 has been deployed. Client and server language packs come grouped into a single bundle containing both client and server resource and support files. You can automatically download the language packs when you're running Exchange Setup.

For organizations that have users in multiple languages, we recommend that you do the following:

  • Install the language pack bundle to provide localized messages on all server roles. This will provide localized messages for Microsoft Office Outlook Web App and Exchange Control Panel. There are no performance issues with installing all the languages because they're just stored when not in use.
  • On Unified Messaging (UM) servers, only install the UM language pack that you need for your organization. The addition of extra UM language packs introduces more processing when the server builds speech grammar for each language.

For a specific language that's supported by Exchange 2010 Unified Messaging, UM language packs allow an Exchange 2010 Unified Messaging server to speak additional languages to callers and recognize other languages when callers use Automatic Speech Recognition (ASR) or when voice messages are transcribed. UM language packs contain:

  • Pre-recorded prompts, for example, "After the tone, please record your message. When you’ve finished recording, hang up, or press the # key for more options." in the language of the UM language pack.
  • Grammar files that are used by a Unified Messaging server to look up the names of specific users in the directory in the language of the UM language pack.
  • Text-to-Speech (TTS) translation so that content (for example, e-mail, calendar, or contact information) can be read to callers in the language of the UM language pack.
  • Support for ASR, which allows callers to interact with Unified Messaging using the Voice User Interface (VUI) in the language of the UM language pack.
  • Support for Voice Mail Preview, which allows users to read the transcript of voice mail messages in a specific language from within a supported e-mail client such as Microsoft Outlook or Outlook Web App.

The U.S. English (en-US) language pack contains UM prompts, TTS, ASR, and Voice Mail Preview support for this language.

The UM language pack must only be installed as an add-in to Exchange 2010 Unified Messaging.

For more information about installing UM language packs, see Install a Unified Messaging Language Pack on a UM Server.

Before you begin your Exchange installation, you must select from these two options in the Setup wizard:

  • Install all languages from the language bundle   This option installs all the Exchange 2010 languages on your selected Exchange server from a language bundle. You then have the option to connect to the Internet to download the latest applicable language pack bundle or to use a manually downloaded language pack bundle from a local drive or network share. Internet connectivity is required for Exchange Setup to download the language pack bundle.
  • Install only languages from the DVD   This option installs only the languages included with the Setup DVD. The installation of additional language support requires installing the languages from the language pack bundle.

You can download the language pack bundle at Microsoft Exchange Server 2010 Language Pack Bundle. After installing the Exchange language packs, restart the computer to complete the installation of the language packs.
