I signed up for an outlook.com account. I can log in to Outlook.com and OneDrive on desktop and iPhone. However, when I launch Photo Gallery, I am prompted for my login credentials. I enter my correct Outlook.com account information but I get a message that "My email address or password is incorrect. Please try again". I am entering the correct credentials. Why does this not work?  If I sign up for a new account it wants me to create another Outlook.com or Hotmail account which I don't want to do. I am using 2-factor authentication but get no messages when trying to sign in from Photo Gallery.
