Resize Outlook Tool

Running a 34" monitor is great unless silly design decisions from programmers make your life a living hell. I mean, who wants a preview pane to be 90% of the screen. This tool made short work of fixing this problem. PLUS it fixes it for the messages list and the folder list... a double win. After you install it there is a resize icon at the bottom of each panel/pane/list and you can drag that to reset the size. Easy as pie!

With my 4K monitor, Outlook.office365.com had the two left panes maxed out at only a fraction of my screen, with all the rest being the reading pane on the right. This lets me properly resize. It's great!
