Thanks for the replies, chaps. It isnt jailbroken and the software is IOS 8.3.1. I have also double clicked the home button and closed the open apps. I have also done a forced reboot and a restore from the settings. I have also deleted the server account and set it back up again. I still hear the emails arrive but still no joy! The mail app is preloaded.....can I delete and then reinstall this app?
