Robohelp 10 and SharePoint 365

I´m testing Robohelp 10 with SharePoint 365.

I configure the Robohelp and SharePoint as the page: http://help.adobe.com/en_US/RoboHelp/10.0/RoboHTML/WS1b49059a33f77726-5aab66613798e5ec9b-8 000.html

On step 3, when I click on "File/Version Control/Add Version Control" and inform "SharePoint Site", user name and password, Robohelp display a message: "Error: The remote server returned an error: (403) Forbidden."

Anybody knows something about this error?

Thanks very much.

Luiza.
