How does this affect me?
You are now able to manage group content produced by setting up retention policies to keep what you want and get rid of what you don’t want. Admins can now create Office 365 Groups retention policies that apply to the group’s shared inbox and files in one step using the Office 365 Security and Compliance Center.
