Getting HTTP 401 Error calling MS CRM 365 USING SOAP UI - microsoft-dynamics

Question

I am trying to call MSCRM 365 web services using SOAPUI, this is what i have done so far
Downloaded Organization WSDL from my cRM instance
Uploaded in SOAPUI
Added three header parameters - Content-Type, SOAPAction and Accept
Added Username and Password in Request Properties
Whenever I send a request to MSCRM, I get "HTTP ERROR 401 - Unauthorized: Access is denied"
Anyone have any ideas?
Thanks,
Nitesh

Since this is Dynamics 365 it does not authenticate using Username / Password. Instead you will need to use OAuth as shown in the link
https://msdn.microsoft.com/en-us/library/gg327838.aspx
// TODO Substitute your correct CRM root service address,
string resource = "https://mydomain.crm.dynamics.com";
// TODO Substitute your app registration values that can be obtained after you
// register the app in Active Directory on the Microsoft Azure portal.
string clientId = "e5cf0024-a66a-4f16-85ce-99ba97a24bb2";
string redirectUrl = "http://localhost/SdkSample";
// Authenticate the registered application with Azure Active Directory.
AuthenticationContext authContext =
new AuthenticationContext("https://login.windows.net/common", false);
AuthenticationResult result = authContext.AcquireToken(resource, clientId, new
Uri(redirectUrl));
Use the access token in message requests:
using (HttpClient httpClient = new HttpClient())
{
httpClient.Timeout = new TimeSpan(0, 2, 0); // 2 minutes
httpClient.DefaultRequestHeaders.Authorization =
new AuthenticationHeaderValue("Bearer", result.AccessToken);
Another options would be to shift from Xrm.Client to Xrm.Tools.Connection. See the example in this site.
