Retention rules are only available to organizations on the Enterprise plan.
Only admins can set a global retention rule. This sets the default rule for all spaces in the organization, and all direct threads owned by the organization. Threads in spaces and direct threads will adhere to this rule, unless a separate retention rule is set for a specific space.
To set a global retention rule from Settings:
- Go to the organization
- Go to Settings
- Go to the Retention tab
