The Open-Xchange OXtender 2 for Microsoft Outlook® lets users keep their familiar Outlook client when their organization moves to Open-Xchange Server. Users feel right at home working with their Outlook interface while in the background the OXtender synchronizes E-Mails, Calendar, Contacts and Tasks, along with Public, Shared and System Folders. Real-time synchronization enables fast response times, so teams can work as efficiently as possible.
The OXtender 2 for Microsoft Outlook uses the newly introduced Open-Xchange Universal Synchronization Machine (USM), which saves the client state and manages the data stream between Microsoft Outlook and Open-Xchange connector. USM only processes the data changes, filters them to ensure fast access and holds them temporarily in cache. The connector software used JSON protocol. Within Outlook MAPI is used, of course, to handle the data. USM is sending information on availability of new objects to Outlook using a sophisticated push notification architecture.
