Did you do a security wipe and not just removed the user and attempted to re-activate? A security wipe remves all previous data from the device including the encryption keys.
Wipe the device first, then delete the user again, run the handheldcleanup tool. Add the user to the BES server and set the activation password (something very simple).
Prior to starting the EA, ensure there's enough coverage (good signal strength) on the device.
Restart the EA process. If this approach doesn't work then try using the wired approach (cradling/plugging into the usb cable).
This is the process the worked for me a few months ago. Once the BES rescans and finds the users mailbox at the users new location everything should start working again.
