Dynamics CRM 2013 ADFS 2.1 with windows 2012 - CRM Outlook client issue

If you configuring ADFS with Windows 2012 you will find that you can't configure the CRM Outlook Client. This is due to a bug in ADFS 2.1 which does not correctly set it's ADFS ActiveMexEndPoint to the correct location.

When you attempt to configure the CRM Outlook client you get:

14:44:16|  Error| Error connecting to URL: https://mycrm.com:444/XRMServices/2011/Discovery.svc Exception: Microsoft.Crm.CrmException: Authentication failed
   at Microsoft.Crm.Outlook.ClientAuth.ClaimsBasedAuthProvider`1.AuthenticateClaims()
   at Microsoft.Crm.Outlook.ClientAuth.ClaimsBasedAuthProvider`1.SignIn()
   at Microsoft.Crm.Outlook.ClientAuth.ClientAuthProvidersFactory`1.SignIn(Uri endPoint, Credential credentials, AuthUIMode uiMode, IClientOrganizationContext context, Form parentWindow, Boolean retryOnError)
   at Microsoft.Crm.Application.Outlook.Config.DeploymentsInfo.DeploymentInfo.LoadOrganizations(AuthUIMode uiMode, Form parentWindow, Credential credentials)
   at Microsoft.Crm.Application.Outlook.Config.DeploymentsInfo.InternalLoadOrganizations(OrganizationDetailCollection orgs, AuthUIMode uiMode, Form parentWindow)

In CRM the information for the ADFS ActiveMexEndpoint it's hold on the FederationProvider table column: ActiveMexEndPoint this information is written every time you configure Claims-Based Authentication. On the MSCRM_CONFIG database run the following command:

select * from FederationProvider

The default url looks like this:
https://myadfs.domain.com/adfs/ls/mex

And you need to update it to:
https://myadfs.domain.com/adfs/services/trust/mex

To udpate the ActiveMexEndpoint run the below query on your SQL database MSCRM_CONFIG database.

update FederationProvider
set ActiveMexEndpoint = 'https://myadfs.domain.com/adfs/services/trust/mex'
