Having trouble connecting Workflow to CRM 2016. We just upgraded our CRM environment from 2010 to 2016 and I am unable to have Workflow 2013 create a new record in CRM 2016. The workflow engine will connect to the CRM environment but when I attempt to create a record, I get the following error from the workflow:
update 184.108.40.206 of Nintex Workflow 2013 which was released on 23rd of July introduces support for Dynamic CRM 2016.
You may install it to give it a try and see if it solves your problem.
