Thank you. I would however again need links to clear explanations (& videos) as to how to do this. I'm also concerned that, as WLM is no longer supported, it will become unreliable.
I am also considering using Windows Mail on my Windows 10 laptop rather than WLM 2012 as this is specifically designed for Windows 10 and is likely to remain supported for some time to come. However I cannot find out whether it is possible to transfer all the thousands of emails I have stored in local storage folders on WLM 2012 on my Windows 7 laptop. These were downloaded on POP3 and the originals deleted from the server so I only have them locally (and all folders exported onto external hard drive for security). I have to refer to these regularly. I know how to export these from WLM 2012 but not whether they can be imported into Windows Mail (Windows 10 Mail). I have six separate email accounts and use POP3 for all as I want to store locally in folders, not on servers. I don't use IMAP. [I have also posted this question separately on October 19th as "Is it possible to import local stored message folders (POP3) from Windows Live Mail to Windows Mail (Windows 10 Mail)"] If importing these stored emails is not possible in Windows Mail then I can't use that.
It is essential to me that I have a (free) email client (host) programme which can support six email accounts (at least), uses POP3, will store emails locally in folders so that I can delete from servers, and will allow me to import my existing stored emails.
Thank you for your ongoing responses and help
