This error occurs when an incompatible version of the SharePoint Connector is installed in Confluence.

Have a look at the plugin compatibility matrix here: https://plugins.atlassian.com/plugin/matrix/235

You will see that versions ending in "jaxb" are designed for Confluence 3.3 and earlier, while versions without the "jaxb" suffix are designed for Confluence 3.4 and later. Installing the wrong one will cause an error like the one you are seeing when trying to connect to SharePoint.
