Advanced Threat Protection feature ZAP not working with spam action "Move to quarantine"
Office 365 security feature zero-hour auto purge (ZAP), which protects against spam and malware is disabled if you use any other spam action except "move to junk folder", because this is one of the conditions for it to work. Want to see that ZAP works with the action to move junk emails to quarantine.
Microsoft is updating Zero-hour auto purge (ZAP) to move phish and spam messages identified post-delivery to Quarantine to better align the ZAP action to the mail flow action defined in the Anti-spam policy.
We can expect this gradually in early October. The roll out will be complete worldwide by the end of November.
