Vulnerability discussion

Office 2013 can be configured to prompt users for credentials to Office365 using either their Microsoft Account or the user ID assigned by an organization for accessing Office 365. Access to Office 365 will not be permitted and only locally installed and configured Office installations will be used.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
