Please bring back support for "linux mailing list" formats
Sending emails to the linux mailing list in outlook for Mac is virtually impossible today due to not supporting a variety of formatting methods that Linux teams require. These are the three key pieces of feedback for the current Outlook apps:
Do not alter the body of the message in transit and in storage. Keep the body of the message after the headers the same, byte-for-byte (no added or removed whitespace or line wrapping).
Outlook in plain text mode has an option to "indent each line of the original message", but only does so with 4 spaces on the left. There should be an option to use the ">" style indent character whether through a specific option for that or with a customizable indent character. It's possible (but cumbersome) to work around this with a text service.
Allow exporting plaintext messages in mbox format (suitable for use with 'git am')
If possible, it would be beneficial to have a "quote" button that does #2.
