In Microsoft 365, anti-spam policies can be used to quarantine messages that are identified as spam, phishing, or bulk emails. By default, these messages are retained in quarantine for a period of time before they are automatically deleted. The length of time that messages are retained depends on the configuration of the anti-spam policy.
The default retention period for messages in quarantine is 15 days. This means that any message that is quarantined due to an anti-spam policy will be held in quarantine for 15 days, after which it will be automatically deleted.
It is possible for an administrator to modify the retention period for quarantined messages by adjusting the configuration of the anti-spam policy. For example, an administrator might choose to extend the retention period to allow for a longer review period or to comply with regulatory requirements.
In the scenario described in the question, the missing email may have been quarantined due to an anti-spam policy, but it is not possible to determine this without additional information. If the email was quarantined, it would have been retained in quarantine for up to 15 days before being automatically deleted. However, if the retention period for the anti-spam policy had been modified by the administrator, the message may have been retained for a longer period of time.
