• Quarantine: Holds messages that are considered potentially dangerous or highly suspicious. These messages have been identified by Microsoft Defender as containing malware, phishing attempts, or other significant threats. Access to quarantine might be more restricted, and notifications are often sent about quarantined items.
  • Junk Email Folder: Contains messages that are identified as spam or unsolicited bulk email. While these can be annoying, they are generally not considered actively harmful. These messages are usually moved directly to your Junk Email folder in your email client.
