I have a problem to generate an MSG-File when the subject of the email contains german special characteres like ä,ö,ü.i. I generate the msg-File and when i save it to disk an reopen it each of that characters was replaced with an question mark "?". I found here an post which describes my problem particular. So at first i was downloading the current version of AsposeNetwork.dll in version 6.6.0.0 and try to generate an MSG-File with your library again. But the behaviour is completly the same. So what can i do to solve that problem ?
Please use MailMessageSaveType.OutlookMessageFormatUnicode as argument when you call MailMessage.Save() method. It will keep the Unicode characters in correct format in subject and body.
