On a recently purchase 8530 Curve, I have established and activated my corporate email account (via my company's IT org) and also set up and connected to my personal Verizon email account.  So there are two separate icons, which is what I wanted. 

But some of my personal email from my Verizon account is now getting delivered to both the BB Enterprise email UI (where it is interleaved with my business emails), as well as being duplicated in the Verizon email list on the BB.  

Any ideas as to how this happened and how i can fix it?
