There really isn’t a concept of just a “hotmail account” today. Your Hotmail account is the login attribute of your Microsoft account.
To get rid of it you need to go to
this information page and follow the instructions. The last part is how to remove the account, but you need to ensure you are not logging in with that account first, or you won’t be able to log in to your pc once you have deleted it.
What annoys me most today is that Microsoft goes to quite some lengths to push you into creating a Microsoft account to log into your PC. Of course you don’t need to but you can’t get to the option not to create an account until you have already asked to create one, at which point only sad IT geeks are looking for the option to get out of doing it.
I checked the options for moving the spam. It’s buried in “Options” form the cog wheel. If you want to look at your account you need to go to the personal icon at the top right of the screen. But that’s just viewing. If you want to delete it you need to go to the link in the article I sent you.
I thought there used to be a cut off for the spam folder, I known Yahoo has one. I’ve set my Yahoo to a week. I’m sure Hotmail used to be able to set it to 24 hours but that option is now gone.
Let us know how you get on.
If you are logged into Hotmail, the mail settings link is
https://outlook.live.com/owa/?path=/options/mailEven if it doesn’t show it.
