Frontend cannot create sub-level mailbox

My final conclusions:
I tried to join Frontend and Mupdate in a single machine and the problem
appeared again, so i believe that i miss something in the configuration
So please, can someone suggest me the right configuration to set
Frontend and Mupdate in a single machine?
I think that the problem may relate to the defaultpartition key in
frontend (I set it to "default") or to the missing comunication between
frontend and his mupdate part on the same machine.
Thank you in advance....
