  • Step 7. Add one or more conditions. The conditions could depend on the subject, keywords, and more

  • Step 8. Add one or more actions and choose to delete the incoming email

  • Step 9. Add one or more exceptions if needed

  • Step 10. Click on “Save”

Once your rule is set up, Outlook will automatically handle those emails for you, so you never have to see or delete them manually again.
