GraphServiceClient graphClient = new GraphServiceClient( authProvider );  
  
var childFolders = await graphClient.Me.MailFolders["{mailFolder-id}"].ChildFolders

    for (int i = 0; i < mailFolders.Count; i++) {   
      
        var mailFolderId = mailFolders[i].Id.ToString();  

        var childFolders = await graphClient.Me.MailFolders[mailFolderId].ChildFolders.Request().GetAsync();
