Hey all,
To start I'm having the exact same issue as in this thread..
http://social.technet.microsoft.com/Forums/lync/en-US/32d53390-ddc3-4eff-8d9e-28554bb475fd/lync-2013-client-not-syncing-address-book
The solution was to install a missing feature install, but that was stated for .net 4.5 for Windows server 2012.
I installed my Lync server 2013 on Windows Server 2008 R2. With a PDC of Windows Server 2003 and a forest level of 2003.
I had issue with every step of the install, from prep schema (x86 environment doesn't like the Lync Deployment Wizard)
Prep Forest (Had to completely remove OCS 2007 from the forest and domain)
Setting up RTC (Mantis didn't document setting up the share folder properly)
and now this, when I finally thought I was done Chapter one I get this issue... anyway
Since I'm not running Windows Server 2012, what could I do/ be missing to get my address book to sync with my clients?
*Note* as in the link, I can add user by full SIP ID!
