I really like the new look of the Win 10 mail app program. I've read however, that it sends the email contents to MS. Correct me if I'm wrong. That may only be if you have a MS account and using Live.com or Outlook email, I'm not sure.

So, for now it looks like I will have to stay with Thunderbird (which looks like its still in the Vista days). "Pity" as the Brits say, would have liked to use the new mail program that came with Win 10..
