Encoding HTML Message Bodies with JIS Instead of UTF-8

This content is no longer actively maintained. It is provided as is, for anyone who may still be using these technologies, with no warranties or claims of accuracy with regard to the most recent product version or service release.

Some applications require the ability to encode the HTML body content with Japanese Industrial Standard (JIS) instead of the default 8-bit Unicode transformation format (UTF-8). In versions of Exchange Server 2003 earlier than Exchange Server 2003 SP2, UTF-8 is the only character encoding used by CDOEX and the ExOLEDB provider. With Exchange Server 2003 SP2, the default HTML body encoding can also be set to ISO-2022 (JIS) encoding.

To use JIS encoding, set the following DWORD registry value to a nonzero integer value:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeWEB\EXOLEDB\UseISO2022JISCodepage

When this registry value is zero, or when it does not exist, UTF-8 is used to encode HTML message bodies. If the registry value exists and has a nonzero value, JIS encoding is used. This change must be made on each server that the application uses to send JIS-encoded e-mail messages.
