Can i know why microsoft decided to stop working on WLM and why it does not work propely anymore with automatic POP setting? 

It only work with manual IMAP setting now, but it's a bit different in speed time etc. and i hate that.
I really don't get why from one day to another microsoft has destroyed it. No updates from 2012 for WLM and i still find it the best email client compared to others like Em Client, Thunderbird, Outlook etc.
