Re: question regarding windows live mail
I can confirm that based upon Microsoft's own support release regarding the "change to outlook.com mail infrastructure" it is only their own e-mail addresses, which are those ending in @hotmail.com, @live.com, @msn.com, and @outlook.com that are affected as far as no longer being compatible with WLM 2012.
If your e-mail service provider continues to use either IMAP or POP either one is fully supported in WLM 2012 (and since it's not being updated except for security fixes it will continue to be supported in WLM 2012).
Never underestimate the difficulty of changing false beliefs by facts.
