Quarantined Emails in Office 365

UConn users that use Outlook for mail will periodically receive information about quarantined mail from Microsoft. These quarantined emails are emails that Microsoft's filters blocked because it determined they were very likely spam or phishing.

When emails exhibit common traits of a phishing attack, such as coming from a spoofed address, Microsoft flags it as likely being a phishing email. If an email has many of these red flags, it is quarantined and not delivered to your inbox. However, occasionally you may want to release one of these emails.

It is important to note that these emails were quarantined for a reason, and you should proceed with utmost caution when releasing quarantined emails. Only release emails from quarantine that you know to be safe.
