            Instructions from KB above are invalid at least for Confluence 6.1.1 and 6.13.3. New macro require more parameters and simple macro name replacement doens't work.

            rachel.x.purpel.-nd: No, it's just Office Connector (and the features of WebDAV itself).

            atlassian.resales: Firstly, we do recommend disabling the WebDAV plugin as a temporary measure only until you can complete an upgrade.

            Until then, disabling the WebDAV plugin will cause the "Edit in Office" button on attachment previews to stop functioning. It will also cause the following macros to stop working: viewdoc, viewxls, viewppt, and viewpdf. These macros can all be replaced with the File Preview macro. This can be done in bulk for your entire Confluence instance by following the SQL instructions on this KB article.

            A customer has come across the following problem while going through our fix recommendations:

            We have come across an issue where even by disabling just the modules for the WebDAV plugin, our users are unable to edit their attachments using the Office Connector. I have a user where she is attempting use the “Edit in Office” option and receives an error of: 

            Any ideas of a way around this?
