Minor Description
While the MESSAGE_FROM metadata field is extracted for both RFC and Outlook emails, it doesn't include the address for Outlook emails.
For example, if the raw from field is "John Doe <john@example.com>", the Outlook email parser sets MESSAGE_FROM to "John Doe" while the RFC email parser sets it to "John Doe <john@example.com>".
Currently I'm getting the from address from the RAW_HEADER_FROM field for Outlook emails, but it would be nice to be able to use a standard across email formats.
