Quarantined Messages and Email Security

You may be getting emails from Microsoft about quarantined messages and wondering what’s going on. The short explanation is that Microsoft’s email filters are getting better and that the company is trying to protect you from harmful attachments and links that can compromise your tech system’s integrity.

We typically don’t know about a message we haven’t seen until the sender contacts us because we haven’t responded to them. In today’s age of more sophisticated phishing campaigns, deep fakes, and more malicious code, we rely on our email systems, such as Outlook and Gmail, to protect us from ourselves with stronger filters. Too many people are careless about opening attachments or clicking links that lead to scams. Even the most careful person can fall victim to clicking on something they shouldn’t. So, Microsoft makes you take an extra step or two in hopes you will slow down and give more thought to the action the sender wants you to take.

It used to be enough to check your spam or junk mail folder in Outlook, and it’s still important with the New Outlook. As filters get more robust, more messages get diverted there, but, as the commercials say, wait, there’s more. You are likely getting messages from Microsoft that they have quarantined messages based on their parameters for determining if a message may be part of a phishing campaign or has a malicious link or attachment.

If you have Office 365, you won’t be able to access the quarantined message in your inbox. Instead, you’ll get a message with the following information for each quarantined message:

  • Sender: The email address of the sender of the quarantined message.
  • Subject: The Subject line of the quarantined message.
  • Date: The date/time that the message was quarantined in UTC.

You’ll also get a link. If you don’t understand what’s going on, you probably feel safer just deleting the message with the link. However, because the filters are more robust – based on an array of factors – you could miss a useful or important message.

Individuals and office administrators who use Office 365 as a web app can find their quarantined messages by clicking on this link: https://security.microsoft.com/quarantine?viewid=Email. It takes you to a Microsoft Defender page where you will see who each message was from and why it was quarantined. Messages are held there for 30 days. During that time, you can release a message, which will send it to your inbox, where you can open it and decide what you want to do. You can also delete a message directly from the quarantine page. We recommend you bookmark this link.

Of course, these security measures put an onus on senders, especially those who legitimately send bulk email, to ensure their DNS records are up to date and follow accepted anti-spam policies for outgoing mail.
