As you may know, Office 365 Groups have been introduced some time ago already. We can view this feature as the replacement of the Mailbox site.
That said, when you create an Office 365 Group it creates a distribution list and a SharePoint site to store the files associated with.
As this site is a SharePoint site, this consumes your allocated storage.
Until now, there was no way to set a quota to an Office 365 Group.
Microsoft has updated the feature and now you can set a storage quota to any Office 356 Group.
As Office 365 administrator, no action is required from you to enable this. The only action you have to follow is to manually set the quota for the group.
To set a quota to an Office 365 Group, follow the following steps:
- Ensure you have required PowerShell modules installed
- SharePoint Online PowerShell modules – available at http://www.microsoft.com/en-us/download/details.aspx?id=35588
NOTE the current version 16.0.4915.1200 has been published in January 2016. As usual, it is recommended to always use the latest version
- Connect to your SharePoint tenant
- Get the site URL for the Office 365 Group
- Set the quota
