Thank you, after testing your response i found it was not compatible with the latest thunderbird version. However on this link https://www.systutorials.com/3165/outlook-style-email-reply-header-thunderbird/ i found the solution. Much appreciated

You're comparing a forwarded message and a replied message – they're going to have different formats because they have different purposes. Are you trying to make the "Reply" quote format more verbose? – user1686 – 2019-03-18T08:30:23.017
This happens to any email, not only forwarded mails. I'm trying to make all the reply's I send to be the same as the screenshot from the forwarded message – toyo – 2019-03-18T08:34:23.913
