Consider this scenario: Microsoft Dynamics CRM 2011 is in a separate Active Directory Domain as the users accessing the application. Authorization to access the Microsoft Dynamics CRM 2011 application is gained through the use of AD FS 2.0 or other federated service identity provider. The Microsoft Dynamics CRM 2011 deployment is configured so that the users in the separate (Home) domain gain access with their home domain credentials or Single Sign On (SSO) information through a federated trust of two AD FS 2.0 servers. The users can access Microsoft Dynamics CRM 2011 through
Outlook by implementing the HomeRealmURL registry key - http://technet.microsoft.com/en-us/library/gg188615.aspx
When configuring the Email Router for Microsoft Dynamics CRM 2011 from the home domain, there is an authentication error when selecting to load data for the deployment using the credentials of a user in the home domain. However, the load data option is successful in the Email Router configuration manager when using the credentials of a user in the same domain as Microsoft Dynamics CRM 2011. Here is an example of the error:
The E-mail Router Configuration Manager was unable to retrieve user and queue information from the Microsoft Dynamics CRM server. This may indicate that the Microsoft Dynamics CRM server is busy. Verify that URL 'https://crm2011.contoso.com/CRM2011' is correct. Additionally, this problem can occur if specified access credentials are insufficient. To try again, click Load Data. (metadata contains a reference that cannot be resolved: 'https://crm2011.contosoft.com/XrmServices/2011/Discovery.svc?wsdl'.)
The Load Data step may be successful with the same user credentials if the Load Data step was completed previously using credentials of a user in the same domain as CRM.
