Using classic Outlook for Windows in business environments
I am also looking for the option to view my list of messages with the Single Line layout in New Outlook. I do not see the option in View>View Settings. I do see a setting called "Message Height", with two options - "Always use Multiple Rows", and "Switch between one and multiple rows based on screen size", but nothing for "Always use Single Line Layout"
I am going back to Old Outlook because i miss how many messages I could scan at a glance with the Single Line layout
