You can use retention policies to group one or more retention tags and apply them to mailboxes to enforce message retention settings. A mailbox can't have more than one retention policy.

Caution:
Messages are expired based on settings defined in the retention tags linked to the policy. These settings include actions such moving messages to the personal archive or permanently deleting them. Before applying a retention policy to one or more mailboxes, we recommended that you test the policy and inspect each retention tag associated with it.
