SYMPTOMS
When you attempt to receive a message that contains Unicode 2.0 characters, the Internet Mail Service may generate an event in the event log that indicates that it was unable to decode the message. This problem is known to occur when you attempt to receive messages from the Netscape e-mail client, but it also occurs when you attempt to receive messages from any e- mail client that uses Unicode 2.0 encoding.



CAUSE
When you install Microsoft Exchange Server, the Multipurpose Internet Mail Extensions (MIME) database entries needed to properly decode Unicode 2.0 messages are not added to the database automatically.



STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 5.0.

This problem has been corrected in the latest U.S. Service Pack for Microsoft Exchange Server version 5.0. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):

S E R V P A C K



MORE INFORMATION
The fix causes the installation program to modify the following registry keys and values:

  Key: HKEY_CLASSES_ROOT\MIME\Database\Codepage\65000 Value name: BodyCharSet Value data: utf-7

Key: HKEY_CLASSES_ROOT\MIME\Database\Codepage\65001 Value name: BodyCharSet Value data: utf-8

After you obtain this fix or a Service Pack that contains this fix, you should reinstall Microsoft Exchange Server. If you do not want to reinstall Microsoft Exchange Server, you can modify the registry as described above manually, but this is not recommended.
