Quarantine retention period is 30 days.

Why This Matters

A 30 day quarantine retention period ensures that administrators have sufficient time to review and release legitimate messages that were incorrectly flagged as spam or malware. If the retention period is too short, critical emails may be permanently deleted before IT can intervene, potentially causing business disruption or data loss.
