Outlook logic for email headers?

Copper Contributor

Does anyone have a design reference about how Outlook displays certain headers in the client; e.g. from, reply-to, sender?    I've found Outlook 2019 and the 365 web client ignore the 'from' field and changes what the end user sees in the 'from' field.   Is there a design doc that defines how the 'from' field is derived?        

 

Thank you,
