Thunderbird works well and it’s free
There’s quite a few free webmails out there. They all do all the things that outlook does. One thing they do even better than Outlook. If you have a hard drive crash you don’t lose all your old emails. It’s impossible to lose your old emails because they are stored in the cloud and accessed through your browser.
So you’re able to access your emails from any machine anywhere in the world on the web. Much better, and easier to use than Outlook.
