Recent security enhancements require the Microsoft Dynamics CRM Online service to use a new certificate to authenticate against the Microsoft Azure service. Use the steps in this article to change the configuration in your Microsoft Azure namespace. These changes are necessary, and will allow the messages sent from the Microsoft Dynamics CRM Online service to the Microsoft Azure service endpoint to be authenticated with both the current certificate and the newer certificate that will be available soon.

Note: This information also applies to the Dynamics Marketing/Dynamics CRM connector integration.

This configuration change should be made before 1AM UTC, Tuesday, November 1st 2016 globally, to ensure minimal impact.

Note: Do not remove the old certificate until after 1AM UTC, Friday, November 4th 2016, as the new one is not valid until this date. However, both the new and old certificates can exist simultaneously without issues.

Note: If your organization is using Dynamics CRM version 8.1 or later, then we highly suggest configuring your service endpoints to use SAS authentication instead ACS. Please click this link for more information.

Also note that if these changes are not made, any integrations to Microsoft Dynamics CRM Online that use the Microsoft Azure Service bus will stop working. Also, if the PluginRegistration tool is used to verify authentication, an error message may occur similar to the following:

“The token provider was unable to provide a security token. The remote server returned an error: (401) Unauthorized”.



When the procedures in this article have been completed, ACS access control will be configured to allow Microsoft Dynamics CRM Online to continue to send messages with the new certificates.


First, retrieve the list of service endpoints. The steps in this article will need to be performed for each of the service endpoints. To find the service endpoints, in Microsoft Dynamics CRM, navigate to Settings, click Customizations, click Customize the System, and select Service Endpoints.
