At the end of the day, the Windows Mail app is still a free version e-mail program – just like Windows Live Mail was. There’s no paid pro version. This app for Windows is not generating revenue for Microsoft like Microsoft Office 365 does. (Think of Windows Mail as Microsoft’s equivalent to Apple Mail on Mac OS.).
Bill GunnI had been using Free eM Client (2 accounts) for a while now. Truly, it has exceeded my expectations. I have a 'relatively slow' Internet connection, and Outlook would fall over repeatedly, timing out, regardless of how I configured it. Thunderbird kind of worked but was a royal PITA to work with (or at least to configure it to the way I wanted it to work).I finally decided to consolidate another external (gmail) account into eM Client, and paid for the pro version - awesome.Most folks usually write something when they want to complain - I do as well (LOL) - but I also like to say Thank You when you get a real good and well supported piece of software.
For a time but they were eventually shut down by Apple. OS X is contractually limited to run on Apple hardware. This means that OS X applications must run on OS X which must run on Macs. There is another project in development called but that does not seek to run OS X apps on Windows but rather to run them on Linux.Edit: Darling side-steps the OS X operating system requirement by translating OS X system infrastructure to Linux infrastructure. This means that you don't actually have to use OS X 'under' the application and therefore the requirement to run OS X on Mac hardware is also side-stepped.
