To run the SharePoint Connector you must update the altassian-extras jar to version 1.20. This is not necessary with Confluence 2.9 as it already has the required jar installed.
- stop the Confluence server
- copy atlassian-extras-1.20.jar to $confluence-installation/confluence/WEB-INF/lib directory
- move or remove any previous jar file from that location starting with atlassian-extras such as atlassian-extras-1.15.jar
- start Confluence
