This means Microsoft Outlook 2003, 2007 and 2010 can talk directly to SOGo — just like if it was a Microsoft Exchange server. No plugins are required in Outlook to make this work. Does that mean we finally have the perfect Exchange killer? A virtual appliance with everything installed and configured is available for download, for testing purposes."
