NAV 2016 integration with OUTLOOK 2013

Hi,
I have integrated MS Dynamics NAV 2016 with Outlook 2013 and I am facing very strange issue:
There are two companies in NAV and if I try to test the connection from OUTLOOK> ADD-INS>Settings>Connection with the first company the connections is successful. But if I try with the other one I get this message:
The connection to Microsoft Dynamics NAV failed. The program returned the following error:
Microsoft Dynamics NAV asynchronous call completed with error: The synchronization failed because the user has no entities to synchronize. Try to synchronize again. If the problem continues, contact your system administrator.; . Synchronization for is not set up in Microsoft Dynamics NAV.
Please verify your synchronization settings. If the problem persists contact your system administrator.


All the setups in NAV for Outlook Synch. Entities and Outlook Synch. User setup are exactly the same in the both companies.

I will really appreciate any suggestions and help because I don’t know what to do. I’ve done everything. 
