 * I am trying to re-authenticate the plugin and I have followed the tutorial exactly
   as it says, several times with plugin delete between to clean the database. When
   I press authenticate and login to my mail, I get a white screen and it just says”
   Application not configured” even tho I have everything setup correctly both on
   our site and on microsoft. Please if anyone know why this is happening, we need
   our mail to work yesterday and I am clueless..
