The SharePoint Connector is not compatible with the Confluence Starter License. The SharePoint Connector license that you purchase must match the corresponding Confluence license. Because we do not offer a starter licence for the SharePoint Connector, the SharePoint Connector will not recognise a Confluence Starter Licence.
As a result, you will see a message like this if you are using a Confluence Starter License:
com.atlassian.confluence.extra.sharepoint.licensing.LicenseException: Didn't recognize Confluence license type (Confluence: Starter). Another type needs to be added to the SharePoint Plugin.
As a workaround, you can get the SharePoint Connector going with an evaluation license. This kind of license will work with a Confluence Starter License.
