Unable to configure the Microsoft Dynamics CRM for Outlook client. (The server might be unavailable. {1}{0})


Errors when configuring the Microsoft Dynamics CRM for Outlook client, "There is a problem communicating with the Microsoft Dynamics CRM server. The server might be unavailable. {1}{0}"  

Trying to open Credential Manager in the Control Panel will result in the following error.  

Unable to save credentials. To save credentials in the vault, check your computer configuration.

Error Code: 0x80070520

Error Message: A Specified login session does not exist. It may already have been terminated.


This can occur if the Credential Manager was disabled either via Group Policy or directly in the registry:


ValueName: DisableCredMan

Value Data: 1


Changing the value Data from 1 to 0, or removing the Value Name entirely will allow the Outlook client to configure correctly as well as allowing the successful opening of the Credential Manager.
