Use the 'info' command in cyradm, like so:

    root at mail:~# /usr/lib/cyrus/bin/cyradm -U cyrus localhost

    localhost> info
       duplicatedeliver: false
       lastupdate:  6-Apr-2016 04:01:01 -0500
       partition: default
       pop3newuidl: true
       sharedseen: false
    *   sieve: global*
       size: 801640500

    localhost> quit

Note the "sieve: global" line.

Yes, happily and consistently, currently with 2.4.10, and up, on various

"...context of a shared mailbox..." doesn't really mean anything here.  
You must do it as a user who has access to the shared mailbox, as the 
page on the website explains.

Take a look at the output of the 'info' command in cyradm, and if it 
doesn't make sense, please post again.

In my experience, the most common cause of problems with sieve and 
shared mailboxes is bad scripts.
