Hello All,

We have integrated Microsoft Dynamics 365 online (v9 latest) with Microsoft Navision 2016, which was working fine till last night.

We observed that something went wrong after applied "Dynamics 365 - Service Update 82Refresh for IND".

After this update We are getting the error in Integration in NAVISION 2016 stating that :

Microsoft Dynamics NAV


The connection setup cannot be validated. Verify the settings and try again.
Detailed error description: The system is unable to connect to Microsoft Dynamics CRM.

Detailed description: Unable to Login to Dynamics CRM.

Kindly let us know, how we can resolve this issue.
