Haven’t been able to receive Hotmail messages since Oct 30, 2013

My Hotmail (Live Mail) account, *** Email address is removed for privacy *** suddenly stopped working on October 30, 2014.  I had made no changes to setting and have checked all filters, forwarding, etc per other discussions.  I have also cleaned out messages from this and two related accounts to insure file storage is not the problem.  The problem is the same when accessing my email on my iPhone and IPad.  This is causing me significant difficulty in several areas and I would appreciate assistance as soon as possible.
