GroupDocs.Conversion provides the EmailLoadOptions class to give you better control over how the source email document will be processed. The following options could be set:
**setFormat** allows you to specify explicitly the type of the source email document. Available options are: Msg, Eml, Emlx, Pst, Ost, Vcf, Mht.
setDisplayHeader specifies option to display or hide the email header.
The following code snippet shows how to convert an Email document and all attachments:
