Are you Missing an Email? It may be Quarantined

This article includes the steps on how to retrieve missing emails from quarantine in Outlook.

M365 Outlook – Why are Emails being Quarantined?

Outlook contains built-in protection that automatically scans incoming emails for spam which may contain phishing attempts and/or viruses.

If an email looks suspicious to Microsoft’s spam filtering tool, the email will be put into quarantine and will not appear in your Inbox.

However, this system isn’t always perfect, and legitimate emails may end up in quarantine. This is why Microsoft notifies you each time an email ends up in quarantine. The image below is an example of this notification that is sent via email.

Please do not remove suspicious emails from your Quarantine. Here are a few tips that will keep you more secure:

  • Never provide your credit card details or login credentials in response to any email.
  • Be cautious of unsolicited emails and links, even if they appear to come from a trusted source.
  • Regularly update your passwords and use strong, unique passwords for different accounts.
  • Ensure your antivirus software and other security tools are up-to-date.
  • Avoid downloading attachments or clicking on links from unknown or unverified sources.
