There is a way to get your exchange mail and calendar in Thunderbird, however I'll be honest I still had issues with the calendar after doing all of this. The calendar would load once, but then not load again. I'm going to provide this for reference. Perhaps in the near future some bugs will be sorted out in these addons, and maybe someone will have a comment on the configuration. I have included specfic versions numbers. If you want GOOD Exchange 2010 support, I recommend using Evolution. There is an Evolution-EWS addition that allows you to use the Exchange Web Services and it works great with mail. calendar, tasks, contacts, etc right out of the box. In Arch Linux the packages are evolution and evolution-ews.
