I updated to Windows 10 and have lost my Windows Live Mail. I've managed to upload a new Windows Live Mail and although I don't understand how, my inbox is getting populated from my bt server including emails that I had deleted on my laptop. It looks likely that eventually it will upload every email I've ever had. The Contacts book has been fed contact details from my linked-in account. These are mostly business contacts that I don't want on my personal laptop but neither the delete or edit function works and I seem to be stuck with them. Is it possible to find and restore my old contact list and my sent emails and email folders?
