Installing the App
The app is available at the Atlassian Marketplace. To install the add-on, log into your Confluence as a system administrator and navigate to the "Find New Apps" tab of the Universal Plugin Manager (UPM) in the global administration. There you simply search for "SharePoint Connector for Confluence" and make sure you selected "Cloud" in the "Hosting Options" dropdown. You can find the UPM via the menu entry "Find New Apps" or similar. For more details about managing apps please refer to the documentation provided by Atlassian.
