One problem is that deleted emails keep returning day after day.
Since around 2013, serious problems with Windows Live Mail 2012 (but not with Windows Live Mail 2011) have been reported on various blog sites (including Microsoft forums). Windows Live Mail is designed to run on Windows 7 and Windows Server 2008 R2, but is also compatible with Windows 8 and Windows 10, even though Microsoft bundles a new email client, named Windows Mail, with the latter. It is the successor to Windows Mail in Windows Vista, which was the successor to Outlook Express in Windows XP and Windows 98. Windows Live Mail (formerly named Windows Live Mail Desktop, code-named Elroy ) was a freeware email client from Microsoft.
