When you reply to a message or forward a message by using a Microsoft Office Outlook client in a Microsoft Exchange Server 2007 Service Pack 1 (SP1), Exchange Server 2010, or Exchange Server 2010 Service Pack 1 (SP1) environment, Japanese DBCS characters that appear in any of the following fields become corrupt:
- The display name of the sender
- The display name of the recipients
- The subject
- The file name of an attachment
- The message body
This problem occurs if the field contains one byte Kana.
The problem also occurs if the message is sent by Outlook Web Access (OWA) in an Exchange Server 2007 SP1, Exchange Server 2010, or Exchange Server 2010 SP1 environment.
Note This article does not list all conditions under which this problem may occur.
