For consistency this would also be clearer if it was:

location = maildir:%%h

Although, do you really have the Maildir/ path included in users' home
dirs? That's not right. http://wiki.dovecot.org/VirtualUsers/Home

You should use IMAP's SETACL commands to change the ACLs. I can't
remember the details of how it works either.

You shared only user1's INBOX to user2. User2 can't see anything else
without user1 sharing them. There's currently no way to set "share all
of user1's mailboxes to user2".
