This isn't working, reverts back to Mail every time. This happening to anyone else? OSX 10.11 El Capitan
Will not allow me to select another mail client for mail default. I select it, close Preferences, then open it again and it doesn't work. Maddening.
MacBook Pro (Retina, 15-inch, Mid 2014), OS X El Capitan (10.11), outlook 15.14.2
