The device is a new one she bought a while back. BUT, today we installed .297, via the AT&T update option. A while back, way back, she did have said email address as a service book on her BlackBerry. But, we removed it quite a while back...
I find this one really odd, and I know my way around a BlackBerry and a BES server. I've never seen this before...
I checked Desktop Manager, and did an advanced restore, but still couldn't see anything relating to that email addres.
Thanks for all the help. We remove all accounts from BIS. Then did a battery pull, and re-added said email accounts. The dodgy email account is GONE from profiles!
