For more information, see Configure anti-malware policies in EOP. ZAP for malware is enabled by default in anti-malware policies. For more information, see Quarantine policies. But, admins can create and use quarantine policies to define what users are allowed to do to messages that were quarantined as malware. By default, only admins can view and manage quarantined malware messages. Watch this short video to learn how ZAP in Microsoft Defender for Office 365 automatically detects and neutralizes threats in email.įor read or unread messages that are found to contain malware after delivery, ZAP quarantines the message that contains the malware attachment. This is another reason to be careful about configuring messages to bypass filtering. Similar to what happens in mail flow, this means that even if the service determines the delivered message needs ZAP, the message is not acted on because of the safe senders configuration. Safe sender lists, mail flow rules (also known as transport rules), Inbox rules, or additional filters take precedence over ZAP. The ZAP action is seamless for the user they aren't notified if a message is detected and moved. ZAP can find and remove messages that are already in a user's mailbox. ZAP addresses this issue by continually monitoring updates to the spam and malware signatures in the service. However, users can still receive malicious messages for a variety of reasons, including if content is weaponized after being delivered to users. Spam and malware signatures are updated in the service real-time on a daily basis. ZAP doesn't work in standalone Exchange Online Protection (EOP) environments that protect on-premises Exchange mailboxes. In Microsoft 365 organizations with mailboxes in Exchange Online, zero-hour auto purge (ZAP) is an email protection feature that retroactively detects and neutralizes malicious phishing, spam, or malware messages that have already been delivered to Exchange Online mailboxes.
