CRM 2011 Outlook plugin fails to configure RRS feed

  • Question

  • When configuring the plugin the Test Connection works but after clicking OK it returns "There is a problem communicating with the Microsoft Dynamics CRM server. The server might be unavailable."

    A line in the trace I believe is the problem is:

    > LoadData failed for URL http://blue:5555/IBS/_root/getUIXml.aspx?client=OutlookWorkstationClient&online=1&savedCredentials=0&signOutSupported=0: Unhandled Exception: System.Net.WebException: The remote server returned an error: (401) Unauthorized.

    I haven't configured a new client in the last two months and clients configured previously still work fine. Even on a working client, if I try to setup under a different user, it fails. If I pull up the url in IE it returns fine.

  • Hi kevin,

    This is possibly related with a change you may have done in the system. Can you check if enabling IIS AppPoolsCredentials to true fixes the problem?

    In IIS highlight the CRM website and open the Configuration Editor

    Navigate to:  
    system.webServer > security > authentication > windowsAuthentication

    Set useAppPoolCredentials to True

    Reset IIS and try again, let us know if this worked.

    Regards
