Sending, receiving, and organizing email in Outlook.com
Hello,
Did you notice any unusual activity in your Microsoft Account?

- "What makes you think that someone has access to your Microsoft Account?"
Use a strong, unique password and enable two-factor authentication for added security. This helps protect your account because even if someone knows your password, they cannot sign in without a second verification method, such as a security code or approval through the Microsoft Authenticator app.
You can enable 2FA by signing in with your @hotmail.com account here: https://account.live.com/proofs/Manage
Alternatively, on the Security Settings page, select the 'Sign out everywhere' option. Microsoft will sign you out of all the trusted devices within 24 hours. So, even if someone has access, they may be asked to sign in and will be blocked on the 2FA page.
You can also have the Same account by adding another Alias to your Microsoft account. So that you can use a different email address (Username) to sign in.
See: How to help keep your Microsoft account secure
If you still wish to close the @hotmail.com account permanently, click the link below and select 'Close Account'.
How to close your Microsoft account
