Retain Groups messages with Vault

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.

To keep data that matches specific conditions for a set time, create a custom retention rule. To keep all service data for all licensed accounts for a set time, create a default retention rule.

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.

What data can be retained

Data that is retained:

  • Messages and their attachments in groups sent when conversation history is turned on

Data that is not retained:

  • Messages in groups sent when conversation history is turned off
  • Messages waiting for approval in moderated groups
  • Linked files
  • Messages in deleted groups
For details, go to Supported services and data types.

Messages in Groups are deleted when the group is deleted.

When a group is deleted, messages in the group are also deleted. 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.
