We want to try different exchange alternatives and found zimbra one of the best solutions. We would like to try this package in order to decide if Zimbra is the best choice. Problem is that we don't use a linux server and there is no knowledge in our company regarding to a trial installation on linux. We've set up a vmware enviroment with ubuntu server but we're not able to install zimbra. We've looked at the demo version of zimbra desktop but that isn't what we need. We want to try zimbra by setting up a simple configuration with 5 mailboxes and shared calendars. Is there some way to experiment with administrator interface without installation of zimbra?
