Microsoft just broke the button that lets you escape the new Outlook client

A while ago, Microsoft rolled out an update that forced everyone's computers to upgrade to the new Outlook app. People weren't pleased, partially because it was done without their consent, but mainly because it was a pretty big step backward from the old app, with missing features and performance issues abound. Fortunately, there's a big "Go to classic Outlook" button in the client that lets you flee this nightmare and go back to more familiar pastures...that is, if the button actually worked.
