I had the same exact problem. If you guys can open the door from inside but not from outside then it is door handle carrier assembly. It is around $87 for part. It's an easy DIY. Need to open door's interior. Do not go to stealer as they will charge $350 for just labor alone. Read instructions, somewhere on X5world, to open the interior and then hidden nuts for door handle. Once you buy and have part in hand, you should be able to figure yourself where most of the nuts should be. Good luck!!
