What are viable alternatives (FLOSS+Mail+Calender+GUI)? I&#x27;ve used Evolution before and it was pretty good, I guess I&#x27;m switching back to that (more importantly I will have to switch my parents&#x27; computers as well, they have happily migrated to Linux). Claws also seems good at first glance.
Have heard KMail and Trojita mentioned before but I&#x27;m not sure how much overhead having Qt for them would be (so basically ceteris paribus I&#x27;d rather have something GTK as Xubuntu is my distro of choice).<p>I guess Exchange integration would be needed eventually but I could work around that if need be.
Linux and OS X support preferred, could live with Linux only.
