This is the worst app I have ever had forced on me for govt email service. Crashes routinely, forces me to re-enter passwords at random intervals, loses the interface to PK reader on regular basis. Since the iOS 10 upgrade, every email I have tried to send has gone straight to the outbox and stayed there, and I cannot get it to do anyone with them. If I never had to use it again it would still be too soon.
