Constant Email Reloading for Android Users

[Android Question]

I have several users who are using Exchange/Active to sync corporate email on their Samsung Galaxy S4. Recently a few have experienced the some form of a system initiated wipe and reload of their email. I have looked at the settings and nothing appears off. The carrier is Verizon and both are the S4.

Any idea what is causing this to happen?

The carrier is probably irrelevant, since the email syncing is probably being done via wifi. Work with the email admin (or IT department or whoever in your company runs Exchange) to try to diagnose the problem.
