Gary Frederick, Leader of the OpenOffice.org Groupware Project says: 'Just to be perfectly clear, this is an MS Exchange take-out. OGo is important because it's the missing link in the open source software stack. It's the end of a decade-long effort to map all the key infrastructure and standard desktop applications to free software.' There are also plenty of screenshots of Outlook, Evolution, Korganizer, iCal etc. accessing the server."
