Microsoft email blocking basic authentication from November?

[king1]

Saw an email from a client about this the other day, I think it was a November? deadline.

Basically means you won't be able to use pop or imap now for MS email addresses eg hotmail, live.com etc  Will require OAuth sign in from then on... 

Newer versions of Outlook, thunderbird etc can cope with it, but older version won't, and Windows Live Mail definitely will not, not that it was much good with imap anyway...
