Consider the following scenario:
- You have a Microsoft Exchange Server 2010 mailbox.
- You send an email message to a recipient by using this mailbox.
- The subject line of the email message contains unsupported encoded characters, such as ISO-2022-JP-2 encoded characters.
This issue occurs because Exchange Server 2010 does not process an email message if the subject line contains unsupported encoded characters. Additionally, an exception occurs when Exchange Server 2010 tries to generate a NDR message.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
