When using Microsoft Exchange Web Service, which requires NTLM Authentication, you may get a 401-Unauthorized error.
If the same web service is called from SOAP UI with the same username and password then the web service call is successful.
This can happen when adding the Basic Authentication policy in the SOA project to the Reference.
