I am running a Zimbra 8.0.3 Network edition on Ubuntu 12.04

I have a Mailbox with 2 Contact folders 1 Folder with about 700 active contacts.
Another folde have about 3000 contacts that are old and only used in outlook.

I have connected a Samsung galaxy S4 with activesync to this mailbox.
In this fone i have now 3700 Contacts. When i am sitting in my Car and connect to my Bluetooth handfree car kit it needs about 40 minutes to sync the contacts.

Is it possible to limit the activesync to onely one folder?
On a IPhone onely the primary contact folder is synced.
