​@rnewman34 if you would need to consider, the mxHERO partner integration with Box would allow you to view any email message stored in Box in a PDF format - inclusive of links within that PDF to any attachments that might have been associated with the email.  mxHERO is a former Box Partner of the Year and the Mail2Cloud platform provided by mxHERO allows you to automate (or manually select) emails (inbound or outbound) for storage within Box including PDF/MSG/EML versions of the email body, all applicable metadata, and attachments.  If you’d like to check that out to help with your PREVIEW rendering or any email-capture use-cases you might have, you can ping me on don@mxhero.com and happy to be helpful.
