As part of your organization's information governance plan, you can control how long messages in Groups are retained. Use retention rules to set how long to keep messages and when to delete them, if ever.
Set custom retention rules to keep data that matches specific conditions for set time. Set a default retention rule when you need to keep all data for a service for all licensed accounts in your organization for a set time. Custom retention rules override default retention rules, even when the default retention rule has a longer retention period.
Important information about Groups and retention
Before you set retention rules, we strongly recommend you read about how retention works and review the Google Groups messages supported in Vault.
WARNING: An improperly configured retention rule can allow Groups to immediately and irreversibly purge messages. Use caution when you create or change retention rules. We recommend that you test new rules on a small set of accounts before you apply the rules to your entire organization.
Messages in Groups are deleted when the group is deleted.
When a group is deleted, messages in the group are also deleted, similar to what happens when you delete a user's account. Messages in Groups are deleted even when the deleted group was subject to a hold or retention rule. However, messages in Gmail that accounts receive through a subscription to a group aren't deleted and are subject to Gmail retention rules and holds.
