Sending, receiving, and organizing email in Outlook.com
Hello, thank you for reaching out to Microsoft Q&A.
To create email rules for Microsoft domain addresses (Such as @hotmail.com, @live.com, @msn.com, @Outlook.com),
Open an incognito/private browsing tab and sign in with your Microsoft account here -
https://outlook.live.com/mail/0/
Go to Outlook Settings > Mail > Rules.
Click + Add Rule,
Name the Rule and add a Condition and action.
So that the junk emails with the specific subject or words will be automatically moved to the Junk/deleted email folder.
Let me know if you still need more help.
