Unable to configure Microsoft Dynamics CRM Clients for Outlook. Configuration fails with the following error:

The specified Microsoft Dynamics CRM server address (URL) is not responding. Ask your administrator to verify that the server is turned on, and then try again.


Microsoft Dynamics CRM 2011 utilizes WCF endpoints for client communications. The WCF endpoints cannot support more than one HTTPS binding.

If the CRM website has more than one binding, CRM Outlook clients will fail to configure.


Open IIS Manager and limit the CRM Website to one http or one https binding.

  1. Click Start, click Run and Type inetmgr.
  2. Expand Sites and click on the Microsoft Dynamics CRM website.
  3. In the Actions Pane click on Bindings.
  4. In the Site Bindings window, ensure that you only have one http or one https binding type. If you have multiple bindings, they need to be removed.


The binding that should remain is the binding that is defined in the Deployment Manager. To check the urls open Deployment Manager, right-click on Microsoft Dynamics CRM and choose Properties, click the Web Address tab.


If IFD is used the Certificate matching your IFD settings should be kept.
