Hey there,
we have some issues in receiving E-Mails from bay176.mail.live.com.
We have 3 live accounts (hotmail.com / outlook.com / live.com) the problem is if we try to send an email from the hotmail.com account and the outlook.com they are sending from dub122.mail.live.com to our Exchange 2010 UR7 SP2 it works but if we try to send from the third account live.com it is sending from bay176.mail.live.com and the mail never reaches our server.
We never get any ErrorMessage from the live.com website or any error in our logfiles.
