  Hi Alan,
  
  in order to access the CRM system from the internet, you have to use the IFD mode. If you configure the outlook client for accessing the crm system via an external address it will not be able to authenticate without the IFD mode.

  We can access the CRM system (not IFD) from internet using IE. just provide the domain account credential. why the crm for outlook can't? it only works in internal network.

  Hi Alan,
  
  see this article for further information:

  CAUSE

  This problem occurs because the Microsoft Dynamics CRM client for Outlook accesses the following URL if you use the An online service provider option:

  http://CRMServer/MSCRMServices/2007/SPLA/CrmDiscoveryService.asmx

  However, if the IP address of the client is included in the subnet that is specified in the InternalNetworkAddress registry subkey, the Web service rejects the access.

   

  If you use the My company option, the Microsoft Dynamics CRM client for Outlook accesses the following URL:

  http://<CRMServer>/MSCRMServices/2007/AD/CrmDiscoveryService.asmx

  However, if the IP address of the client is not included in the subnet that is specified in the InternalNetworkAddress registry subkey, the Web service rejects the access.
