My Contacts in WLM has untold duplicate entries for whatever reasons, but I CAN'T DELETE THEM!

 Messages (10 pages worth) go back to 2012 in the "Community", but there are no no useful answers.  THey all want to blame Skype, whatever that is.

So I have to move to some other email service, but WLM also doesn't let me save my Special Folders, in which I've stored valuable emails for years.  Any suggestions?
