Working in NAV2015, Outlook Add-in/Microsoft Dynamics NAV Synchronization Add-in. In outlook settings, I’m getting success with Authentication Type of Basic. However, with Authentication Type of Windows I get this error when testing the connection;
---------------------------

The connection to Dynamics NAV failed. The program returned the following error:
Dynamics NAV asynchronous call completed with error: The request failed with HTTP status 401: Unauthorized.; . Synchronization for is not set up in Dynamics NAV.
Please verify your synchronization settings. If the problem persists contact your system administrator.

Any suggestions would be appreciated.
