We use a pop mail server for our email at our company. I have a user that uses outlook 2013. They also have an iPhone. When she would enter in a new appointment or accept an appointment in outlook calendar it would show up in the iPhone calendar program. That was on iOS 8.2. She upgraded to iOS 8.3 and now this functions does not work. Is there something I can do to fix this or is their a 3rd party program that would solve this problem? I know that changing her outlook account on both sides to imap would probably fix this as well but she does not want to have email received that way.
