I've used hotmail for like 15 years, and I had a lot of old sentimental emails stored in my account. I used it sort of as a storage for all my old stuff when I got a new account. I signed in every now and then to make sure things were in order still. I somehow missed the notification of the switch over to Outlook. So when I went to sign in a few days ago, I was shocked to see that everything (folders, saved stuff) in my account had been deleted and that I now had outlook.
