I have been having similar problems.  I have recently upgraded the OS to Win10 Pro and did a complete clean reinstall.  I installed Windows Live Mail which was working fine for a few weeks.  However after changing my Store Folder, Windows Mail will not now run on that PC.  I have installed Live Mail on another PC and copied the contents of the old Store Folder to it.  This one is running OK.

On the original PC whenever I try to run Windows Mail I get the same error message "Windows Live Mail could not be started.  Closing Windows Live Mail.  Your calendar contains corrupt data that is forcing Windows Live Mail to close (0x80070057)".  I have tried renaming my ...@live.com email address as shown in %localappdata%MicrosoftWindows Live MailCalendars but that didn't help.  I also renamed my Store Folder.  Now when I try to run Live Mail, a new folder is created with the same name as the Store Folder in the same location.  That folder contains, among other things a log file, these are the contents: Log opened: 2016-03-11T20:29:23Z
