Dovecot LDA delivers to users.

So, IMHO, in this situation I would add another userdb{} of type 
passwd-file, which adds a fake user office3 and uses the Maildir 
.../Public/.office3 as INBOX. If that fails or turns out to be 
problematic, setup another complete new user home directory like all 
others and symlink cur and new to Public/.office3 (and tmp, if they reside 
on different mount points).
