Thanks for the hint.
However the explanation does not convince me.
The first run of offlineimap does both things correctly: it creates the 
folders and syncs them.
It recreates the folder hieararchi from the remote Exchange repository 
into the local Archivio rspository.

I do not understand why, repeating the process and using the same 
configuration (i.e. same source and same target) it should create 
folders within the Archive folder that it created in the first run.
The operation should be idempotent.
It should always start from the remote repository and create the folders 
in the same place as before, not within the new folders it created in 
the first run.

What it seems from the error message it is trying to copy a folder that 
does not exist in Exchange, since Archivio is only present in Ateneo:

'Archivio/networks/CAF' (repository 'Exchange'). The latter becomes
'Archivio.Archivio.networks.CAF'

How can this be explained?
