Hi @Holly Robinson
Glad to hear this issue has been resolved and thanks for the sharing!
However, due to a update in forum policy, the question author now is not able to accept their own answers.
So, I have written a brief summary of the solution this issue. Please feel free to ACCEPT it as the Answer, which would benefit others who also have similar issues in the forum.
Issue:
Outlook Reply does not leave room to write and includes reply text in sender header.
Solution:
Outlook / Settings / Composing
Then under Replies/Forwards; Attribution of original message
Choose "Custom" (you can leave what is prefilled).
It will change the look from the full address info to original sender email.
