Hello everyone,

I noticed on the emails Quarantine page the following:

Is the a MS general issue? or is it unique to this tenant? Do you guys have any idea how to troubleshoot this?

Any input is appreciated.

Thank you!

    Seems to display fine here. Can you check via PowerShell and the Get-QuarantineMessage cmdlet? If it's displaying the same therein, best open a support case.

    Hi @Said A ,

    How long does it actually take for a message to expire in quarantine?

    You can check the details of quarantined emails in your organization via the Get-QuarantineMessage cmdlet to see if they are the same as those shown on the emails Quarantine page.

    For reference: Get-QuarantineMessage.
