For those that are having Exchange Email issues with the Kit Kat update, there is an app I just tried that may help. Mail Wise - Beta, in the play store https://forums.androidcentral.com/e...ils?id=com.syntomo.email&hl=en&token=Lav5c4Wq
The app functions quite nicely and has a clean look in the interface. I have been using it all morning and so far it has worked perfectly. The app is currently free and worth a try if the stock app is not working for you. In my case, I had no issues with the stock app but I like this one better. Additionally, there is a security bypass that allows you to sidestep security requirements that are sometimes imposed by Exchange.
