Hello @GA,
Azure does not automatically create Resource Groups in your subscription. The unexpected Resource Groups are likely created by services you deployed, such as Managed Applications. You need to identify the parent service creating the Resource Groups and delete that service first before you can delete the Resource Groups.
You can use Azure CLI or Azure PowerShell commands to list and delete:
Azure CLI
- To list all resource groups:
az group list - To delete a specific resource group:
az group delete --name <ResourceGroupName>
Azure PowerShell
-
Get-AzResourceGroup -
Remove-AzResourceGroup -Name <ResourceGroupName>
