I upgraded to Windows 10 about 3 weeks ago but decided to go back and downgrade to Windows 7.  I've now discovered in Windows Live, that I've lost all my emails which were saved in Folders.  Each time I open Live Mail, a message appears stating that there was a corruption and data is being recovered.  Well it's obviously not being recovered when I don't have any emails saved in my folders.

I've tried reverting to previous version etc but nothing working.

Can anyone help please?

Thanks

Carol.
