Quarantine email notifications have stopped as of July 2023

Question

I'm wondering if it's just us or if there's some kind of outage not mentioned in the 365 Admin Health area.

The last ones which came in, according to a trace, were on June 30. There have been quarantined emails daily this month, so there obviously should have been notifications about them.

As before, "Send end-user spam notifications" in the Global Settings of the Quarantine policy has "Within 4 hours" selected.... NotificationEnabledPolicy and DefaultFullAccessWithNotificationPolicy are Enabled, as always.

Hi @rpodric , thanks for posting in our Q&A forum.

It seems to be backend issue, but it is suggested that you can follow the below troubleshooting steps:

1. Check the user's other folders, including Deleted Items and Junk Email. It might be best to do a search through the entire Inbox and all subfolders.
2. Also, check the "Recover Deleted Items" option in the Deleted Items folder.
3. Check the quarantine (O365 Security & Compliance --> Threat management --> Review) to confirm that there are new messages for which notifications should be sent.
4. Please run the message trace and check whether there are any quarantine notifications were sent to your account.
5. Temporarily disable any additional spam filter policies you may have configured (O365 Security & Compliance --> Threat management --> Policy --> Anti-spam settings).
6. Temporarily disable the End-user spam notifications. Leave this disabled for a few hours before reenabling it.

And I have found a similar post here for your reference: https://answers.microsoft.com/en-us/msoffice/forum/all/not-receiving-o365-quarantine-notification/535a2eab-20ac-4b65-abe7-a77ff8a3b6fa If there are any update, please feel free to let us know.

Unclear why my previous response is not showing above, but disabling/enabling did nothing. However, deleting the quarantine policy and recreating it did.

I wouldn't have thought to try that, but in another forum someone else with the issue contacted support, and they ran an "EOP sync" to correct the problem (unclear what that is) but said that if it happens again to delete/recreate the quarantine policy.

Hi @rpodric

Glad to see that your issue had already been resolved and thanks for sharing the solution so that others experiencing the same thing can easily reference this! Since the Microsoft Q&A community has a policy that "The question author cannot accept their own answer.

Though it's hardly the final solution since the number of notifications sent only cover a minority of the actual quarantined mail.
