Windows 8.1 Enterprise upgrade: You can’t keep apps?

Reading Time: 3 minutesI think I might start a new tradition: every time a major/important OS or update is released, I try find out how to block it from Exchange . Now, I know the Mail app has been around for some time now. If you recollect, I did some research on how Exchange ActiveSync (EAS) within the Mail app works in general and how it implements security settings in Windows 8.
