CRM 2011 Outlook Client Server Address (URL) is not Valid

During a new CRM 2011 installation using IFD/ADFS we had everything running properly for a about a week and then IFD access broke. Users could no longer connect via Outlook. They were all getting the following error message.


Where the HTTPS:// was known to be correct as we could login via IE.

This error message points to KB2548802 – Configuration of the Microsoft Dynamics CRM 2011 Outlook client fails with the error: “The server address (URL) is not valid”

We confirmed issues 1 & 2 in the KB and checked the resolution.

This issue can occur due to the following reasons:
1. Anonymous Access is disabled on the CRM web site.
2. The Web Address URLs specified in the Deployment Manager do not match the CRM URL in IIS.

We were good on #1 and #2. Time to do more research. We then went to  this support article – KB2498357 Microsoft Dynamics CRM 2011 Outlook client configuration fails with “The specified Microsoft Dynamics CRM server address (URL) is not responding”. What caught our eye in this article was the platform trace error example was identical to what we were seeing even though the error message was different. Our trace error looked like this:

Error Exception : Metadata contains a reference that cannot be resolved: ‘https://<ServerName>/<OrgName>/XRMServices/2011/Organization.svc?wsdl’.    at System.ServiceModel.Description.MetadataExchangeClient.MetadataRetriever.Retrieve(TimeoutHelper timeoutHelper)

The resolution in this KB was to check the Site Bindings and ensure thaat you only have on http: and/or one https:// binding type. We checked and we only had one of each. But since we weren’t using the HTTP:5555 url anymore we removed it and then we could connect via Outllook.

So the answer at least in this situation was that if you don’t need the legacy binding any longer – remove it and it could solve the Outlook configuration issue.
