I'm having problems with calendar synchronization of all devices Iphones my company, happens the following situation:

When an agenda for the Iphone device is created and sent to other recipients, they receive and accept everything works normal and is scheduled at the Iphone device, but this book is not transferred to the Exchange owa and consequently does not appear in Outlook on the user's notebook.

Managers had cases lose important meetings because of this problem.

I have installed here in 2013 with Exchange Server replication DAG.

I will be very grateful if someone manages to give me a direction to solve this problem.

Take a look at these articles, there are a number of issues with ActiveSync and third party implementations of the APIs.
