running WIndows Live Mail 2012, on Windows 10

today lost( disappeared) three months of inbox email( since May 2017), but not email I have saved in folders

is this in the Message Store Mail.MSMEssage Store( which I found was created today 8/22 and is 50 Meg)

I use my *** Email address is removed for privacy *** as my user name to log in and have a live.com account, which does not work

been having some problems since I think MS does not support Windows Live Mail anymore

anyway how do I recover these inbox emails?

or can I port my entire live mail folders to another  mail application?
