Thanks for the fast reply! With cyrus, shared mailboxes are shown as 
user.mailbox or user/mailbox

This is a client setting. With Outlook 2013/2016 it is possible to use 
activesync but you can only choose sync one month or all. With setting 
one month, it is not possible to get older data from the server. With 
setting all, all shared imap folders get downloaded via active sync. 
This is no fun with a huge shared mailbox. I had the vast hope, that one 
can influence the cache settings from the server, if it is not possible 
to disable the shared mailbox completely.


Best wishes,
