How do I connect to and exchange 2010 server using technologies other than .Net?

I need to access exchange 2010 calendaring services from a thunderbird plugin. The web services are missing their "services", apparently they are all kept in ExchangeServiceBinding class. Any ideas on how to connect to these services using anything other开发者_如何转开发 than .Net? We have skills in python, php, java and can learn a few more.

DavMail (<http://DavMail.SourceForge.net>) would be another option.

Personally I have only used Active Directory and Email Service. The following link might help to read calender service using Java:
