Consider the following scenario.

•	An e-mail message has the header field and the body field set to different character sets.
•	The two different character sets do not belong to the same language group.

When you try to view the message by using Microsoft Outlook, the body of the message is garbled.

For example, a message has UTF-8 specified in the From field or in the To field. Additionally, the body of the message is encoded as ISO-8859-1. When you try to view it by using Outlook, the body of the message contains garbled characters.

This problem occurs because Microsoft Exchange Server 2003 sets the PR_INTERNET_CPID property to the UTF-8 character set. The PR_INTERNET_CPID property is a superset for any header field character set and body field character set. When a message uses two different language groups, Outlook tries to display the body of the message in UTF-8. Therefore, the body of the message is garbled.
