Hi at our organization we are having issues with sending HTML messages with Japanese characters. The contents of the message is garbled. This only impacts messages sent to external users, not internal and only HTML messages.
We run Exchange 2007 SP3 on our mailbox and hub servers.
The client is sending the message using Outlook 2007.
In our environment due to restructuring we have 2 mailflows to external users.
Exchange 2007 --> MailMarshal --> Postfix --> Messagelabs --> Internet
Exchange 2007 --> MailMarshal --> Iron Port (IMG) --> Internet
When sending from Outlook through both mail flows the problem occurs.
On our MailMarshal servers we use Outlook Express client to send mail and we have no issues.
We then used Outlook Express client on our desktop to send a message through our application mail servers which delivers it to our Exchange 2007 Hub servers then to MailMarshal and internet and we have no issues which leaves us to think the issue is with Outlook 2007 or Exchange 2007.
If we send the message to Gmail we have no issues, if we send to yahoo mail we see the issue so it is just some external users that are having problems.
Is there anything we can do to ensure that no matter which client an external user is using HTML messages with Japanese characters can be read properly? Would language pack on Exchange server make a difference?
The attached file shows how the message looks like in Outlook when sending internally, then how it looks in Gmail and finally how it looks in Yahoo where the problem occurs.
