How-To
Task: View and Act on messages in the Quarantine Email list
When you receive messages from Microsoft 365 security saying you "have messages in quarantine" there will be links within the email for you to respond. If those links do not work or if you want to check on your quarantined messages at some other time, use these steps.
Instructions
Step 1 - Open a web browser and go to https://security.microsoft.com/quarantine
Note: If a link doesn't work at first, try a private browser or a new browser window, or clearing your browsers' cache
Step 2 - A list of quarantined email messages is displayed.
- If an email you believe to be quarantined does not show within your quarantine list, it may be found in your Junk folder.
- If it is not found within quarantined or junk mail, it is possible that the Focused Inbox feature has sorted it out and that it is under the Other section.

Step 4 - Click the desired action link at the top of the list. Link availability depends on the details of the selected message. You always have the option to Delete or Preview messages.
