How can I eliminate the need to horizontally scroll in order to view the outlook email

[johnnyalogy]

Originall outlook mail (hotmail) displayed the current email without any need to scroll horizontally. the latest Outlook now displays the current email with the need to horizontally scroll. this is quite a bother so I would like to know how to remove the scrolling necessity.

Maximise the window so it fills your screen.
