Hosted Exchange Autodiscover/ActiveSync services do not work:

1. Customer is getting an error in their smartphone that the password is not valid.
2. POA CCP shows unforeseen error at Top > Exchange > Mailboxes
3. Trying to reconfigure the device POA CCP shows the same unforeseen error of error about invalid password.

Autodiscover URL ( gives error message:

500 System.Net.WebException: The operation has timed out at System.Net.HttpWebRequest.GetResponse() at AutodiscoverProxyHandler.Handler.ProcessRequest(HttpContext context)

Event Viewer on Exchange CAS servers shows error like this:

WebHost failed to process a request.
 Sender Information: System.ServiceModel.Activation.HostedHttpRequestAsyncResult/55761063
 Exception: System.UriFormatException: The protocol binding '[::1]:80:' does not conform to the syntax for 'http'. The following is an example of valid 'http' protocol bindings: ':80:'.
   at System.ServiceModel.AsyncResult.End[TAsyncResult](IAsyncResult result)
   at System.ServiceModel.Activation.HostedHttpRequestAsyncResult.End(IAsyncResult result)
 Process Name: w3wp
 Process ID: 9896



Wrong binding [::1]:80: is configured on the default website in IIS on CAS servers. It was probably added by some Exchange update.


Remove wrong binding [::1]:80: from the default website in IIS on CAS servers.
