Alternatives to Windows Live Mail for Linux with any license

Thunderbird

Thunderbird is a free, open source, cross-platform e-mail, news and instant messaging client. The project strategy is modeled after Mozilla Firefox.
- Thunderbird have not Outlook's express / Live Mail's simplicity. Thunderbird is like evolution Light. Very detail settings. When "some" not work, you cannot write and save draft. Guest • Oct 2016 • 2 agrees and 0 disagrees
- Among other things, no provisions to open non-system folders to keep different files. You can open one but it doesn't let you type or delete, or in general work on it. It's passable but very far from being similar to WLMail. :) Guest • Sep 2018
