Quarantine inaccessible: Error message: Failed to load data. Please try again later.

Theodore Rand 5

For several weeks, I have been unable to see data in https://security.microsoft.com/quarantine quarantine. This problem started suddenly as I was previously able to access quarantine. Simultaneously, my team started receiving emails affixed with the "first point of safety" notification - i.e., "You don't often get email from..." I have not made any changes to our Defender or to Exchange that would explain the issues we are having. I reported this to Microsoft Support two weeks ago and they have not assisted in resolving this. I am the admin on an account using Microsoft Business Premium. The issue occurs regardless of the network, browser, computer, etc.

Hi Theodore,

not entirely sure what the issue would be in your case but have you tried clearing your browser's cache then accessing the quarantine page? Or accessing it via an incognito/private window. See if the issue persists.

Also, you could check that the service health in the Microsoft 365 admin center to see if there's any ongoing issue related to Microsoft Defender or Exchange.

Try also accessing the quarantine page from a different network to rule out a scenario where access may be blocked by some firewall/network security settings.

I have had the same problem for weeks as well now.

One day the previous search list just randomly started working, but outside of that, it's not been functional for a few weeks now.

Hi David,

thanks for letting us know that you are experiencing the same issue. Have you filed a support ticket with Microsoft over this issue internally? If so, you could share the ticket and I could follow up. If not, I will try investigating internally.
