I am referring to replyTo, this is extracted from graph explorer:
"toRecipients": [ { "emailAddress": { "name": "", "address": "" } } ], "ccRecipients": [], "bccRecipients": [], "replyTo": [ { "emailAddress": { "name": "", "address": "" }
There is no Office.context.mailbox.item.replyTo, there is Office.context.mailbox.item.from and Office.context.mailbox.item.sender.
Desired behaviour:
ReplyTo list shown in graph explorer on an email can be extracted using add-in API.
