CRM 2011 outlook client setup error RRS feed

  • Question

  • Hi all,

    I've seen a few posts on here regarding issues with the outlook client for CRM 2011 throwing errors while the external web access works fine with the same authentication but I've not yet seen anything which resolves the issue for me or shows the same error in the log so thought it best to start a new thread. 

    I'm using windows 8 CP and have confirmed with others that after enabling windows identity foundation 3.5 the outlook plugin works fine (see here:

    After enabling Windows Identity Foundation 3.5 I expected things to run smooth, but I' still getting the dreaded "cannot connect to Microsoft dynamics crm as we cannot authenticate your credentials......." error so I turned on tracing and found the following:

    • >Exception during Signin System.ServiceModel.EndpointNotFoundException: There was no endpoint listening at that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. ---> System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

    Now I dont understand why a connection is being tried on port 80 for authentication, but surely this should be using port 443 just like the web interface login? 

    We only have port 443 open for ADFS, can someone offer any help?
