Easy hotmail in karmic!!
so its not that difficult after all - just use PRISM!
log into hotmail on your browser - copy the http: line and add it to PRISM then add your login detail and Voila! all ready to add to the task bar!
ok so not the most in depth how-to but if youve been messing about with all the different email apps using Prism will be childs play! if not just message me and ill add more detail.
