Offline Compatability
Offline functionality is not available in the CRM 2011 client when working with CRM Server 2013 or 2013 SP1/Spring 14.
When the 2013 client is not running SP1 and the 2013 server is running SP1/Spring 14 the client uses a pre-update snapshot of views, forms and navigation for components affected by the new product features when offline.
