We are glad to announce that Extradium, the flagship extranet user management for on-premises SharePoint, now supports SharePoint 2019, on top of SharePoint 2013 and 2016.
Starting with v188.8.131.52, Extradium will support the 2013, 2016 and 2019 versions of SharePoint with one single installer. However, a separate end user license (and license key) is necessary to use Extradium with each major version of SharePoint.
Along with this new support addition, we are officially removing support for SharePoint 2010, as of January 1st, 2020. All customers currently on SharePoint 2010 are invited to upgrade to a more recent version of SharePoint, and follow our Extradium 2010 to 2013 migration instructions available in the Extradium Upgrade Guide. Note that the Extradium installer compatible with SharePoint 2010 remains available for download for existing customers but is no longer supported.
