Recently staff have lost the ability to block senders via the quarantine@messaging.microsoft.com email that is sent to their inboxes.
This option is also greyed out in the defender portal for them as well.
We have a policy in place that is supposed to allow this action so it is not clear as to why this is not available.
I did find an article stating that MS is taking this away by default however creating a policy should allow this i would think. I am looking for feedback on anything i may have missed.
Thank you in advance.
Thank you for your response.
Are you aware of any delay from when the new policy is created and applied to the time users are able to see the changes?

Hi，
I'm glad to receive your reply. I tested it and theoretically the policy is effective immediately, but considering the network issues, I suggest you wait 24 hours.

Hello, it's been a long time since I've heard from you, did my previous reply help you, if it was useful, you can mark it as an answer. Thank you for your understanding and support.
Hello.
Sorry to say that this did not work and i am still trying to find a solution.
Hi
1.Did you create a new policy and it still doesn't work?
Hi Bruce
I created a new policy and the experience is the same. Screenshot of the policy is below.
Hi，
I'm glad to hear from you.
First of all just creating a quarantine policy is not complete, you also need to create an anti-spam policy and add the new quarantine policy to the anti-spam policy.
Yes. I created the new quarantine policy and added it to the default antispam policy. Since that did not correct the issue, today I created an new antispam poicy and applied the new quarantine policy to it and after several hours i am sad to say that there hasn't been a change.
Thanks for your reply.
Hi，
I'm glad to hear from you.
Thanks for the screenshot of your anti-spam policy.
Based on the screenshots, it looks like there's nothing wrong with your setup. To fully understand your anti-malware policy, the following cmdlet commands can obtain specific parameters.Please provide a screenshot of the result of the cmdlet command below.
2.Use Get-HostedContentFilterPolicy -Identity "PolicyName" | Format-List to get the specific parameters of the policy.
Hi，
I checked the official Microsoft documentation and it is recommended to create a new quarantine policy if the NotificationsEnable Policy is not in effect. You can refer to this URL for the exact steps:
