Quarantined email

What is a Quarantined email? 

You're probably familiar with Microsoft Outlook's Junk folders for email. By default, phishing, spam, and bulk email messages are directed to your Junk Email folder, which is a good reason to review this folder daily.  Sometimes junk mail enters Quarantine because the message is potentially dangerous.  These types of emails are "Quarantined" as a precaution.  

 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. If you do not release a message from the Quarantine, it will automatically be deleted after 30 days.

What to Expect:   

If email messages addressed to you were sent to Quarantine, you will receive an email notification from Quarantine@messaging.microsoft.com or Quarantine@Sunyempire.edu with the subject line "Microsoft 365 security: You have messages in quarantine” or "You have messages in your SUNY Empire email quarantine" in your mailbox.   The email provides you with a list of the messages addressed to you that are stored on the Quarantine page within the M365 Security & Compliance Center.   You can look at the message subject headers to determine their content and decide what actions you want to apply to the messages.   If you don’t know the sender, you can block the sender using the buttons within the notification. If you know the sender and have verbally verified they did send the email with an attachment or link, you can release it to your inbox.   After thirty (30) days, the quarantined messages will expire and be deleted.  

How do I delete my messages in the Quarantine? 

There is no need to delete your messages in the Quarantine. If you do not release a message from the Quarantine, it will automatically be deleted after 30 days. If you look at the messages in your Quarantine location and determine that all of them are unwanted, you do not need to do anything. The messages will automatically be deleted from the Quarantine.
