If the orphaned team or group is:
Active - ShareGate sends the new owner an email to let them know you've selected them as an owner.
Inactive - ShareGate sends the new owner an email to let them know you've selected them as the owner, and asks them to decide whether the team or group should be kept, deleted, or archived.
Note: The option to archive a team or group is only available if you have set up an Azure storage account to store your data. For more information, see Archive overview.
