Okay... I'm sure this is something simple that I'm missing. My app works fine in preview mode, however, when anyone tries to use it, they are taken to a loginlive.com, suggesting a personal email address. All users are getting the same issue, including myself, and when we enter our organizational email, it tells us it doesn't exist. We have a OneDrive for Business, and that is where my data is saved. Why does it want my personal email???
