Microsoft to Windows Live Mail 2012 users: Switch now
Found on Infoworld on Sunday, 08 May 2016

Windows Live Mail 2012 users are on notice: Switch to a modern email client or lose access to any Microsoft email accounts they have.
Ironically, Gmail users will be able to still access the Windows Live Mail 2012 client -- that service operates with the older protocols supported in Windows Live Mail.
Imagine a world where there would be well established and implemented protocols for something like emails; who knows, maybe one could name them SMTP, IMAP or POP3.
