I have been using Windows Live Mail 2012 running under Windows 10 since February 2016 without any problems.  For some reason, beginning during the last week or so, my mail in the Inbox, Sent and Trash has been disappearing without me deleting it.  I need some of this history but where is it going - I cannot seem to find it and have not found any answers from Microsoft or the Microsoft Community.  If it is anywhere I would appreciate someone letting me know where it is or what do I need to do to stop this from happening? 

Also, I see in the Microsoft Community that Windows Live Mail will not be supported to run in Windows 10.  I have never received any notice of this from Microsoft and will have big problems if this is true by June 30th!!!!!  What is going on from Microsoft with all of this kind of announcements?

I have not found an easy way to convert to Outlook.com from Windows Live Mail 2012.  If I need to do this where is the documentation?
