Windows Live Mail Error 0X80072EFF

I'm using Windows 10 and Windows Live Mail that loads my Hotmail, Msn and Googles accounts.  No problems until yesterday when I can no longer access my Hotmail account.  I get the 0X80072EFF error message.  Msn and Google load with no problems.  When I try accessing the 3 accounts in Outlook, I get the Msn and Google accounts but not the Hotmail.   Can access all 3 on my Windows phone and on my android tablet.  A week ago Microsoft contacted me via email with a notice that my MSN account showed 3 different instances of someone in Minnesota trying to access my account .  (I was shopping in a Target store at that time and figured Target was trying to tinker with me thru my Windows phone which is a scary thought in itself).  I changed my password for my Microsoft account but had no email problems until yesterday.  Any suggestions that are easy for a non-tech person?  Thanks.
