We are designing a C# based exe utility, which will download mail in following format: -

.

      ii- Embed attachment with mail body

    Task: - If Attachments are embedding, and then we need to dump attachments and body as body.mht

.

     iii- Embed attachment within mail body, and also having separate attachment in mail

   Task: - Separate attachments will be saved in some folder and embed attachment, message body will be saved as body.mht

1. Check the property on the Attachment https://msdn.microsoft.com/en-us/library/office/dd633665(v=exchg.80).aspx itself. Depends what you mean by embedded do you mean Exchange Store types ? these are called ItemAttachments in EWS.

2. see https://msdn.microsoft.com/en-us/library/office/dn672317(v=exchg.150).aspx which has a sample of saving a message as an MHT file.
