If you have not received a quarantine report, this can be due to a few different reasons.

You currently have no e-mail in quarantine

The quarantine report is only triggered if an email was saved in the quarantine after the last report. If this is not the case, no report will be sent. This avoids sending empty quarantine reports.

Check whether the report has been configured correctly

To do this, navigate to Email Security in the Control Panel and then to Spam & Malware Protection > Quarantine Report.

Check the settings:

1. Is the quarantine report activated?
   
   
   
2. Will a report for the whole domain be sent?
   
   If this is the case, a report will only be sent to the stored e-mail address, other mailboxes will not receive a report.
   
   
3. Which delivery times are activated?
   
   It is advisable to have the report sent at least twice on working days.
   If the users are allowed to set their own delivery times, then you need to check the delivery times of the user. You can find them under Settings > Mailboxes > respective user > Quarantine Report
   
   
   
4. Have the delivery times been deactivated?
   

Check whether the mailbox concerned is stored in the control panel

A quarantine report can only be sent to a mailbox that is stored in the control panel under Customer Settings> Mailboxes. 

In addition, the mailbox must be active in order to receive a report.

If none of the above steps seem to resolve the issue feel free to contact the support responsible for you.
