E-mail sync on/off not working

[cj1896]

Ok, so I have my exchange account e-mail set up with my phone and it syncs with my phone (I can send/receive, sync calendar, etc). My problem is that I can't get the on/off for the sync to work correctly. Sync does work correctly for my gmail account.

If I leave the email app open in the background it will still receive messages even with sync off. If I have sync on and the app isn't running in the background I can't receive any messages.

I have tried excluding it from my task killer and this results in me not being able to turn sync off.

I can't remember how it was working when my phone wasn't rooted because I did this right around the time that I first rooted the phone. Any help is appreciated.
