When using the SubmitFile method of the OfficialFile.asmx service, I was returned this value: NotFound

NotFound

Simple fix was to add my account to the Records Center Web Service Submitters group on the site.

Healthy return message from the service:
“Successhttp://site/_layouts/DocIdRedir.aspx?ID=AHVCF7U4ZST3-8-55&hintUrl=myLibTestA%2ftest1_2F4IOO.docx”

Good example on how to upload load files to the Drop Off Library using OfficialFile.asmx service.
