Hi @Claus Trillingsgaard ,
do you have backups of the Azure resources related to the deleted Resource Group? For instance an Azure Backup of Azure VMs or Azure databases?
That's the only way I am aware of to restore Azure resources if deleted.
As far as I know there is no way to recover/restore resources after successfully deleted in Azure without having a backup.
