Restoring a Deleted Event
If you wish to restore a deleted event, first navigate to your Dashboard and view the "My Follow Up" panel. At the bottom of this panel you will see initial information on "Events Deleted in the Past 7 Days". Expand the option and to restore, just click on the event in question. From here you can also view all deleted events, and restore as required. See this video.
