Hi @Giuseppe ,
Welcome to our forum!
What do you mean about "new Outlook 2023"? Is it New Outlook for Windows when you turn on New Outlook button?
Previously, I attempted to use the shortcuts "Ctrl + End" or "Ctrl + Home" to navigate to the desired position, but unfortunately, they did not work as intended.
If so, based on my test in New Outlook for Windows, i can use "Ctrl + Home" and "Ctrl + End" to select the first or the last email in the emails list (include Archive folder). Please try to repair your Office programs and check if you can do this.
Additionally, I have noticed that using the scroll bar on the left side of the screen does not allow me to swiftly move to the opposite end of my email list.
What do you mean about the croll bar on the left side of the screen? If possible, please provide a screenshot of it for our better research. (To avoid your privacy leakage, please remember to hide your personal information.)
