Sync two shared contact folders within one machine


Outlook version
Outlook 2010 64 bit
Email Account
Exchange Server
Hi Everyone,

I help manage two databases of contacts and each database contains over 5000 contacts within Outlook 2010. We use Microsoft Exchange Server with Outlook and I have access to both contact folders from my computer within Outlook. I would like to synchronize both those contact folders within my machine in Outlook. Is there any software that enables me to synchronize multiple folders within my machine in Outlook? Any help or suggestions would be greatly appreciated :).
