      I transitioned all ove my computers from Windows to Linux. I had 4 computers so I used four different distributions with different linux bases, Debian and Arch. Thunderbird worked perfectly. The email client is awesome, I think they should devote more development efforts to calender and task management integration.

      Can202 ThunderBird es la mejor alternativa open source, ya que puedes personalizarlo, mi recomendación es usar la extención CheckBox, Thunderbird junto a CheckBox (extensión), la mejor APP para Mail

      Fast and User friendly. Light-weight and classic menus really give a touch of old classic office 2003. Easy integration of mails especially exchange mails without facing any bottlenecks.

      Support for EWS allows me to connect to exchange and get all the benefits like contacts and calendar I wouldn't so easily get on Thunderbird. Also it nicely integrates with the built in Ubuntu calendar as well which is a big plus.

      I've found it better than thunderbird and it can work with exchange just with one free plugin

      This would be the best alternative, except that it requires the Gnome desktop, so users of other desktop environments need to look elsewhere.

      Beautiful theme options with custom designed themes available. I tried thunderbird a few times but always came back to mailspring. I LOVE the "views" feature that shows you how many times an email was opened and if it was forwarded by the recipient!
