Default [Q] Exchange on non-encrypted device

Hi guys,

I am using my work e-mail on my SG2+ device running latest stock 4.2.2, rooted. As an app I use the stock Android mail client. Recently I got the news from the administrator, that the mail policy has been changed and I have to encrypt my device in order to continue using the mail on my mobile phone.

Is there any app/method, which I can use in order to bypass the encryption and continue using the Exchange on my device?

Your answers are much appreciated!
