Thanks for the reply i didnt think the 2nd account would be possible and really was a sort of last resort idea.
If i can definetly get the old handheld wiped even after i delete the user from the BES and activate them on a new blackberry then thats what i will do.
I was under the impression the user account was the link between the BES Server's queued command and the blackberry and after removing them i was worried that the Blackberry would not get wiped.
So thank you , you have solved the problem
