2 days ago, I was suddenly unable to access Hotmail using Windows Live Mail with IMAP.

What change did Microsoft make to its IMAP server 2 days ago?

Background -

For the last 2 days, I cannot sign-in to Hotmail using Windows Live Mail (WLM) with IMAP in Windows 7.

By going to OUTLOOK.COM (in my web browser) I can still sign-in. But using the WLM app I now get this 0x800CCC0F error:

"XOAUTH2 authentication failed. None of the authentication methods supported by your IMAP server are supported on this computer."

How do I reconnect my hotmail account to Windows Live Mail ?
