Having an eMail with an Outlook attachment, i.e. an attachment with content type message/rfc822, when i try to extract that attachment with the method Multipart.getInputStream() I will not get the attachment as an Outlook file, i.e a .msg file, but rather I get a file which consists of the eMail-Text of the Outlook attachment.

Is there a possibility to extract the attachment as an Outlook file ?
