Final answer:
In Microsoft Outlook, messages considered spam are sent automatically to the Junk Email folder, which helps filter out potential threats and can be adjusted by the user.
Step-by-step explanation:
Messages that Microsoft Outlook deems to be spam are sent automatically to the Junk Email folder. This functionality helps protect users from unwanted or potentially harmful emails that may contain phishing attempts, viruses, or other malware.
The Junk Email filter can be adjusted to suit user preferences, and emails that are mistakenly sent to the Junk Email folder can be marked as 'Not Junk' to inform the filter of the user's preferences.
