XADM: Exchange Server Corrupts Japanese cc:Mail Message Subject Routing It to the Internet

ID: Q237838

The information in this article applies to:

SYMPTOMS

When you set up an Exchange Server computer to be the SMTP gateway of a Japanese Lotus cc:Mail post office, if a cc:Mail user sends a Japanese message to an Internet address, all Japanese characters become question marks (?) at the receiver side.


CAUSE

When the message is exported from Lotus cc:Mail to Exchange Server, all content is converted to UNICODE. But the native code page information (CPID) is not saved, so the default Windows NT CPID is used instead.

When the message is converted from UNICODE to the native code page by Internet Mail (IMAIL), all the message properties are converted to the default CPID.

If the computer running Windows NT Server is running the English version, all Japanese characters are converted to question marks.


RESOLUTION

A supported fix that corrects this problem is now available from Microsoft, but it has not been fully regression tested and should be applied only to systems experiencing this specific problem. If you are not severely affected by this specific problem, Microsoft recommends that you wait for the next Microsoft Exchange Server version 5.5 service pack that contains this fix.

MORE INFORMATION

Steps to Reproduce the Problem

  1. Install a Japanese Lotus cc:Mail post office.


  2. Install an English Exchange Server 5.5 Service Pack 2 computer on a computer running the English version of Windows NT 4.0 Service Pack 4.


  3. Set up the Internet Mail Service, and configure the attachments as MIME.


  4. Configure the Microsoft Exchange Connector for Lotus cc:Mail to connect to the Japanese cc:Mail post office, and set the post office language as Japanese.


  5. Configure the Exchange Server computer as the SMTP gateway of the cc:Mail post office.


  6. Log on to the cc:Mail post office using a Japanese cc:Mail client, and send a message in Japanese (including the Subject line) to an Internet address.


Result: All the Japanese characters in the Subject line, as well as in the To, Cc, and any other properties are corrupted.

If you use UUENCODE in the Internet Mail Service, the problem does not occur because all properties are using the same CPID as the body, which can handle the CPID correctly.
