I am trying and failing to integrate Nav 2018 (on prem) with Dynamics 365 sales. Navision 2018 is updated to the latest version.
I have seen posts and guides refering to a plugin/solution that should be added to CRM but I could not see the name of this particular plugin/solution.
The account used to perform the connection has the system admin and system customiser roles within D365 CRM and it also is a non-interactive account and we have checked with and without a license assigned.
The error recieved is shown below.
