Tarleton Email Quarantine (Microsoft 365 Defender)

Tarleton State University utilizes Microsoft 365 Defender, Microsoft’s solution for email protection. This solution defends our users and systems from malicious emails that could possibly compromise computers, infrastructure, and data.

Quarantined Email Notifications

Once a day, you may receive an email quarantine notification via email with the subject:

"Microsoft 365 security: You have messages in quarantine"

A quarantine notification email contains the following information for each quarantined message:

  • Sender: The sender email address of the quarantined message.

  • Subject: The subject line text of the quarantined messages

  • Date: The date and time (in UTC) that the message was quarantined.

  • Review Message button: Clicking Review Message takes you to the Quarantine page in the Security & Compliance Center, where you can (depending on why the message was quarantined) view, release, delete or report your quarantined messages.

  • Release button: For spam (not phishing) messages, you can release an individual message. See note below regarding how to "Never Block Sender"

  • Block Sender button: Click this link to add the sender to your Blocked Senders list.

Email Quarantine Folder

The quarantine folder holds potentially dangerous or unwanted email messages. You may access this folder at any time - it is not necessary to wait for the daily quarantine message. You can view, release, and delete quarantined messages where you are a recipient, and the message was quarantined as spam or bulk email.

To view emails in the quarantine folder, visit Microsoft 365 Defender

The following actions can be taken on quarantined email:

  • Release message – Releases one or multiple selected emails

  • View message header – Allows viewing of the email header for analysis

  • Preview message – Allows email to be viewed in HTML with all links disabled or in plain text

  • Download message – Allows a copy of the email to be downloaded to the local computer

  • Remove from quarantine – Deletes a single or multiple selected emails from quarantine
