What changes

Outlook MSG email is parsed by our mail engine and rendered as HTML with headers made explicit for msg-to-html.
Subject, From, To, and Date become a visible header block or Markdown table before the message body.
MSG files are read with msgreader, so Outlook-specific fields outside the parsed message body may be omitted.
HTML email bodies are sanitised for scripts and style noise; tracking pixels and client-specific rendering are not reproduced.
Attachments are not embedded into the converted body; the page should be treated as message content, not an archive bundle.
HTML output stays text-oriented and is best for review, search, or archiving message content.

Example

input

Outlook MSG message with Subject, From, To, Date, HTML body, and attachments

output

HTML export with a headers table and sanitised body; attachments are listed separately

Do it in code

cli
