The Microsoft® Exchange Server Analyzer Tool reads the following registry entry to determine the language settings that are used by Microsoft Outlook® Web Access clients:
The UseRegionalCharset registry value causes UTF-8 message bodies to persist in the store in the regional character set or codepage instead of in UTF-8 format.
The Exchange Server Analyzer also queries the Active Directory® directory service to determine the value of the serialNumber attribute for all objects that have an object class of msExchExchangeServer. If the string value includes "Version 6.5", the computer is running Exchange Server 2003.
If the Exchange Server Analyzer finds that the UseRegionalCharset is configured to use a value of 0 on a computer that is running Exchange Server 2003, the Exchange Server Analyzer displays a non-default configuration message.
This message indicates that the UseRegionalCharset registry parameter on this Exchange 2003 server is disabled. This setting may cause unintended character set encoding for Outlook Web Access messages, where some messages may be unreadable by some clients.
When you use Microsoft Internet Explorer 5 or later versions to access Outlook Web Access, Exchange Server 2003 uses the browser's language settings to determine which character set to use to encode information such as e-mail messages and meeting requests.
If you expect Outlook Web Access users in your organization to send mail frequently to recipients who use a variety of character sets, you can modify the registry settings so that users who are running Internet Explorer 5 or later versions can use UTF-8 encoded UNICODE characters to send mail.
