Email and Calendar keeps reloading
We have multiple instances of Iphone's running IOS 7 and ActiveSync to an Exchange 2010 server where every calendar entry just disappears then 10 seconds later it is back.
Email acts the same. Launch the email app and it will show no messages then all of sudden they will start downloading just like when you created the account the first time.
We have deleted and re-added the account on the Iphone we deleted the pairing of the device from the Exchange server.
The kicker is that is does not happen all the time. Our Android or Windows phones have no issues, it started doing this several weeks ago and it is happening to dozens and dozens of our phones and Ipads.
iPhone 5s, iOS 7.1.1
