When users submit via webservice, they are getting the error below Warning The form cannot be submitted because of an error. Click OK to resume filling out the form. You may want to check your form data for errors. An error occurred while trying to connect to a Web service. An entry has been added to the Windows event log of the server. Log ID:5567 Correlation ID:bdf4fa9c-2914-30e3-0811-57ff993b90a4 The form works correctly if users submit from InfoPath directly, But the aforementioned occurs ONLY When users submit via webservice &amp; The users whom have tested have FULL Control permissions! I checked the Correlation ID, and I found: DataAdapterException, Exception Message: The remote server returned an error: (401) Unauthorized. The remote server returned an error: (401) Unauthorized.) Could you please guide me on how to resolve and fix this issue ?
