This presentation will focus on, how Zarafa will be integrated in the existing PLUS Infrastructure-as-a-Service and how management of the application can be deferred completely to the local independent entrepreneur. Zarafa is the European open source replacement for Microsoft Exchange. Consider you don’t want IT administering to configure your messaging platform? What should be done? The roll out for our shops will take place in January 2012.
