Windows Live Mail End of Life
Microsoft’s Outlook Team announced on May 5th, 2016 that the Windows Live Mail application will reach it’s End of Life (EOL) on June 30th, 2016.
The immediate effect of Windows Live Mail being retired is primarily that any Microsoft email accounts — @outlook.com, @hotmail.com, @live.com, or @msn.com addresses will not be able to be accessed using the Windows Live Mail 2012 email client after this date as Windows Live Mail does not support the Exchange ActiveSync (EAS) protocol. Also, there will be no future security or bug fixes for this product rendering it potentially dangerous to continue using for other email accounts.
It is strongly recommended that current users upgrade either to the default Windows Mail app in Windows 10, or Outlook 2016 before this date to prevent disruption in email services. An alternative is to use the third-party eM Client that supports the new Exchange ActiveSync (EAS) protocol that all Microsoft email accounts will be using exclusively as of July 1st, 2016.
To clarify, Windows Live Mail will still continue to work in the near future with your email accounts at Scarab Media, Ashland Home Net, Open Door Networks, or Project A, although it will no longer function with any Microsoft email accounts. It is still strongly recommended to consider upgrading to a different email client nevertheless.
