Dynamics 365 breaks the OOB connection between Dynamics CRM 2016 and Dynamics NAV 2016

I must say I was a bit surprised when one of my colleagues told me the following issue. Navision refuses to make a connection with Dynamics 365 if you are using the Out of the box connection for Dynamics CRM 2016 and Dynamics Navision 2016. This issue will be resolved in  the next NAV Update Rollup, but you should be aware of this product defect!

The issue:

  • The customer is using the CRM Online and the NAV machine.
  • The customer opened the Microsoft Dynamics CRM Connection Setup window to connect the NAV to his CRM Online organization.
  • The customer got “The connection setup cannot be validates. Verify the settings and try again. Detailed error description: Invalid Request.” error message when test the connection to the instance organization.
  • If you connect with an other Dynamics CRM environment (8.1), this works fine.
  • Microsoft engineers don’t know if the issue would be fixed by upgrading NAV 2016 to NAV 2017.

The cause:

Know issue – Product Defect

The resolution:

The NAV team will provide the proper fix for this issue in the next Update Rollup which will available around end of December.

    The link is for the Connect site for the Preview program for Dynamics 365 for Sales next release (CRM 2017). So if you don’t have a preview org, you probably don’t have access to the site.
    If you are a part of the preview program just use the same credentials for Connect as for the preview org.
