I got myself worked up today because I encountered the "loose space" in my Outlook and thought it was because my display had some how become misconfigured. Sometimes I normally saw that behaviour when I'd remote in from my iPad and the display would change so at first I thought I was the cause. I even made this thread: https://answers.microsoft.com/en-us/msoffice/forum/msoffice_officeinsider-mso_win10-msoinsider_outlook/spacing-in-new-email-view-is-huge/84c923d2-043e-4109-b977-47e357b6f9c4?messageId=39dc1a52-de88-4a8c-b139-d1fd43ae72de I got Office 365 support involved and I even reinstalled Office! I dont know why anyone would want this "touch" feature on Outlook for desktop. I understand that some users have laptop tablets but that should be an opt in function. Even with the "tigher space" there is still a lot of white space.
