Categories for sending emails to groups of people are an essential feature of Windows Live Mail for me. These worked perfectly until last Friday, when they disappeared. Had difficulty downloading the Windows Live Mail fix from Microsoft as recommended in email late 2015. I then downloaded Windows Live Mail 2012 and all the updates to enable me to download the fix.  This enabled me to recreate categories but, each time I either logged off or went onto Outlook.com to check, the earliest category disappeared.

I posted this problem here before but got unhelpful reply saying that groups are no longer available. I objected to this and got another reply with an apology but redirecting me back to this site, so I seem to be going round in circles.

I find it difficult to believe that Microsoft would remove a functionality, namely the ability to send emails to designated groups ( Categories in Windows Live Mail).  Before I have to give up completely on Microsoft for emails, can someone please explain how I can create and retain categories.

PS I am not an IT expert. I use Windows 10, which was fine until this problem cropped up.
