 With this configuration 
 
 namespace {
  disabled = no
  hidden = no
  ignore_on_failure = no
  inbox = yes
  list = yes
  location   mailbox Archive {
    auto = create
    autoexpunge = 0
    autoexpunge_max_mails = 0
    comment     driver     special_use = \Archive
  }
  mailbox Archives {
    auto = no
    autoexpunge = 0
    autoexpunge_max_mails = 0
    comment     driver     special_use = \Archive
  }
  order = 0
  prefix   separator = /
  subscriptions = yes
  type = private
}
namespace {
  disabled = no
  hidden = no
  ignore_on_failure = no
  inbox = no
  list = no
  location = 
mbox:/home/mail-archive/%u/Archive/:CONTROL=/home/mail-archive/%u/Archiv
e/control:INDEX=/home/mail-archive/%u/Archive/index:LAYOUT=maildir++
  order = 0
  prefix = Archive/
  separator = /
  subscriptions = yes
  type = private
}

I get this error message from apple mail when I right click and choose 
archive
"The IMAP command "UID COPY" (to Archive) failed for the mailbox
"INBOX"
with server error: Mailbox isn't selectable"

If I add the inbox=yes, the dovecot logs are flooded with 
Error: namespace configuration error: There can be only one namespace 
with inbox=yes
namespace configuration error: There can be only one namespace with 
inbox=yes in=0 out=398

Did you notice that you have a mailbox called 'Archive' and namespace
called 'Archive'? Namespace roots are not selectable, and this looks
more like a config error.

That is been done on the advice I got here. 
Since November I am trying to get resolved, that I need my Archive and 
subfolders on different storage location as the default. Furthermore 
Archive folder is being used by apple mail, Archives folder eg. by 
Thunderbird. So it would be nice to 'group' this, so Thunderbird is not 
accidentally storing this on the default storage.

If the aliases plugin was working properly, I could have done this maybe 
via aliases
