SYMPTOMS
Outbound SMTP messages from the Internet Mail Service may contain 8-bit data in the message body, even though the Internet Mail Service is configured to use UUENCODE and the US-ASCII character set.
CAUSE
The 8-bit data should be mapped to the 7-bit equivalents. Outlook 98 introduces a property that incorrectly signals the Internet Mail Service to use the ISO8859-1 character set, instead of US-ASCII.
RESOLUTION
To resolve this problem, obtain the latest service pack for Exchange Server version 5.5. For more information, please see the following article in the Microsoft Knowledge Base:
191014 XGEN: How to Obtain the Latest Exchange Server 5.5 Service Pack
The English version of this fix should have the following file attributes or later:
Component: Store File Name Version ------------------------- Store.exe 5.5.2438.0 Mdbmsg.dll 5.5.2438.0 Gapi32.dll 5.5.2438.0 Store.exe 5.0.1461.75 Mdbmsg.dll 5.0.1461.75
STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange Server versions 5.0 and 5.5.
MORE INFORMATION
The Internet Mail Service will encode outbound mail according to the following criterion:
- If the Internet Mail Service is configured as MIME, the Internet Mail Service encodes the 8-bit data in either base64 or quoted printable.
- If the Internet Mail Service is configured to send UUENCODE and the outbound character set specified is US-ASCII, then the Internet Mail Service will take the 8-bit data and match it to the closest 7-bit equivalent.
- If the Internet Mail Service is configured to send UUENCODE with the outbound character set specified as ISO-8859-1, then the 8-bit data should be left in the body of the message.
