I just received a message in our Office 365 tenant:
New feature: Office 365 Groups files quota management
Office 365 Groups: files quota management is a new Office 365 feature. You’ll begin seeing this new feature today.
How does this affect me?
Today, Office 365 Groups files consume from your organization’s SharePoint shared storage quota; team sites and groups share the same available capacity. You now have the ability to set quotas on groups’ underlying sites to help manage the consumption of shared storage by Office 365 Groups’ files.
What do I need to do to prepare for this change?
You don’t need to do anything. Please click Additional Information to learn more.
That’s great news, very exciting to see this feature is on it’s way 🙂
