Microsoft Exchange Replacements (Score 1)

There are some fine products which are available as a replacement for the Microsoft Exchange. E.g. Troyzen WEB Organizer is the WEB based application which has all the functionality of the Exchange and more (and it is considerably much more reliable - I think it's running on Linux server and it has been entirely written in Java). I think that you can still try demo @ www.troyzen.com, click on demo and username and password will be readily available for the test drive. Cheers.
