You may already know that you can recover a deleted Office 365 Groups using PowerShell during the 30 days retention period.
This does not change but it is becoming a bit easier by using Exchange Online ECP.
As for the restore with PowerShell, the following is recovered when the deleted Office 365 Group is recovered:
- Azure Active Directory (AD) Office 365 Groups object, properties and members
- Group SMTP address
- Exchange Online shared inbox and calendar
- SharePoint Online team site and files
- OneNote notebook (if used)
- Planner (if used)
To recover the group and also see when it has been deleted, connect to Exchange Online ECP with your Global/Exchange administrator account (https://outlook.office365.com/ecp)
Go to the Recipients\Groups section and look for the Group type Office 365 Group (for the purpose of this post I have created an Office 365 Group named “RecoverECP”
After the group is deleted, it will be showed with a new status Deleted XX days ago where XX means the number of day since it has been deleted
And on the right side, a new option to recover the group is now available
Then you will need to confirm the recovery process
