Why does the system not store anything into the 'Quarantine Store' folder?
If a rule is set up to block and store detected messages to the Message Store, everything is working fine. But if the Message Store response object is changed to the Quarantine Store response, the system does not store anything in the Quarantine Store folder.
Storing to a Quarantine Store folder only works if the recipients in the appropriate rule are also contained at Mail Security > Policy > Quarantine Report Recipients. If not, the rule still will fire but it will not store the message to the Quarantine Store.
