Mimecast tables, queues, and viewers display information on email data for a specific length of time. A summary of these is displayed below:


MenuQueueRetention Period
MonitoringStripped Attachments

Based on the retention period of your account. This includes all attachments that have been held, stripped or stripped and linked.

Rejection ViewerSeven days
Connection AttemptsSeven days
Bounce ViewerOne month
Held Queue

14 days. 

Once emails expire from the Hold Queue, they are still available in the Archive for the retention period of your Mimecast account.

Delivery Queue
Delivery retry for six attempts (or one hour) after which a warning message is sent. After 30 attempts (four days) the delivery will fail or soft bounce.
GatewayAccepted EmailTypically two to six hours, at which point a successfully delivered email is archived. Alternatively, emails will remain in Accepted Email until they reach their final state (i.e. delivered successfully or failed in delivery).
TrackingAdministrators are only able to search back across the last 30 days of data.

Archive RetentionMaximum Retention

This is populated as part of the implementation process based on your purchased Mimecast Service. Preservation Policies (content and metadata) can also be used to decrease the retention period for specific users / groups or domains.

User retention and retention adjustments allow you to purge emails based on their lifespan. Litigation Holds can be used to override all purge policies.
