Received an email from Microsoft about a quarantined message?
Did you receive a notification that an email sent to you has been placed in quarantine? If the notification is from firstname.lastname@example.org, you don't have to worry. Microsoft placed this email in a safe online environment, because the email may be spam or may be a phishing email. In this online environment you can review the email safely without any risks.
How it works
The notification from Microsoft includes information about the sender, the subject line and the date and time of the quarantined email. After reviewing it, you can choose between a couple of different actions: block the sender, release the email (this is only possible if it's a dangerous email) and send it to your own mailbox or review it. By reviewing it, you will open the email in the safe online environment and here you can choose whether to release, delete or report the quarantined email.
As long as you don't take action on the notification from email@example.com, Microsoft will continue to send you a reminder every three days. Messages will be held in quarantine for 30 days, after this they will get deleted.
Do you prefer to manually review your quarantine notifications yourself? You can find more information on how to do this in the helpdesk portal.
