My oulook was deactivated by a hacker for only few minutes, when reactivated, first email was welcome to outlook and 10yrs worth of Emails had gone!

I had spyware on my computer,

my email was fine, then I received emails form my own account to myself, then I couldn't access it,

When I could get back into it, there was a welcome to oulook email and all emails, folders had vanished,

It was only few minutes from deactivation to reactivation, I need to get the files back
