im not sure if it was fixed in the code of the devices, but i know there was an issue that devices with content protection enabled could not have their passwords reset. it was a known issue with bes and certain versions of handheld code.
That is correct, but that was happening in pre-4.6 OS's. With 4.6 and up this problem was solved. But even with the new OS's we see it sometimes that the Password status sticks on "Received". If you do the password reset again after some minutes, it works for us.
