I got a HTML body string from exchange through MAPI. The message code page equal 50222, HTML charset is ISO-2022-JP, I used 3rd party lib UncodeString::extract and CkCharset::convertHtml all cannot convert correctly. I want to know whether there are ways to resolve this issue? How to use MS API to solve it?

Hi As far as I know, exchange can't convert html body string. You can also post your question to outlook forum. http://social.technet.microsoft.com/Forums/en-us/outlook/threadsTerence Yu TechNet Community Support
