Get rid of security settings

[gtsps]

So I have an HTC snap. My work forced a security setting on my phone so it automatically locks like every 15 minues and I have to enter an 8 digit code to unlock it every time.

I've tried to deselect this function but it will not allow me to.

Is there a way to dissable this feature so that it doesn't lock and require so many key strokes every time to access my phone yet make my companies software think it is enabled so that I can still connect to the exchange server to get my e-mail etc?

Thanks for any help!
