Problem Sending from Live.com Outgoing Server

I have not been able to send an email or picture from my mobile device since last Friday from my live.com account. If I try to send something or forward or reply to any incoming email, it says Cannot Send Mail:  The user name or password for "SMTP:  my *** Email address is removed for privacy ***@smtp.live.com" is incorrect.   I have checked everything that I know how to check and have updated my passwords and made sure there weren't any changes or anything wrong.  I am receiving all incoming, I simply can't respond or send.  Has the Outgoing Host Name of the server changed from smtp.live.com and I simply need to put a new outgoing server name in my device.  Thanks for any assistance, as I use this phone regularly for work and have been stuck since last week.
